Constellation Optimization for the Non-Linear Fiber Channel
Creators: Soleimanzade, Amirhosein
Publisher: name: University of Alberta Library
Year: 2022

Due to the exponential growth of Internet usage and inefficiency of the traditional modulations, the capacity of the current optical fiber networks is not sufficient for future Internet demands. As a result, increasing the capacity of the fiber networks is of great importance. Since most of the available bandwidth of fiber systems has been occupied, improving the spectral efficiency (SE) of the fiber channel is an appropriate approach to increase the capacity. Constellation optimization (also known as constellation shaping or constellation design) is an efficient SE enhancement technique, and has two important categories: (1) probabilistic shaping and (2) geometric shaping. Probabilistic shaping changes the uniform distribution of the constellation points into a non-uniform distribution. Geometric shaping relocates the position of the equiprobable constellation points such that the achievable rate increases. In this thesis, we propose two constellation optimization methods. The first method is a geometric shaping method that maximizes mutual information (MI) of the amplitude-phase shift keying (APSK) constellations. We optimize APSK constellations for the additive white Gaussian noise (AWGN) channel and non-linear fiber channel. For the fiber channel, the optimization is performed at the maximum modified signal-to-noise ratio (SNR) of the optical system. By doing so, our optimization algorithm maximizes the MI rate while the impacts of shaping on the non-linear interference noise (NLIN) power are considered. The second shaping method is a hybrid method that combines probabilistic shaping and geometric shaping. Our hybrid method maximizes the generalized mutual information by considering the impacts of shaping on non-linear interference noise. We show that our hybrid method outperforms both geometrically and probabilistically-shaped constellations.
Mortality among the Canadian population with multimorbidity: a retrospective cohort study
Creators: Xiao, Xiang

Year: 2022

The association between multimorbidity and mortality was well established based on the previous studies. However, there is limited evidence of excess mortality in people with multimorbidity among the Canadian population, and a study with a larger sample size is recommended. Furthermore, it has been recommended to examine multimorbidity mortality among individuals under the age of 65, as some research

demonstrated that it has become a serious issue for the middle-aged population as well. Therefore, this thesis examined the association between multi-morbidity and mortality based on the linked database of CCHS (Canadian Community Health Survey)-CVSD (Canadian Vital Statistics Death Database) which included a study sample representative of the general population of Canada. The results of the study suggest that people with multimorbidity had a significant lower cumulative survival probability in comparison to those without multimorbidity during the 14-year follow up period, after adjusting for all confounding effects. The effects of multimorbidity on mortality increased from the oldest (65 years old and above) to the youngest age group (35 to 49 years old). Additionally, when the interactions between different chronic diseases were considered, it was found that subjects with COPD and without diabetes had a significantly higher risk of death in comparison to those without COPD and diabetes. This risk was further increased in

subjects with both COPD and diabetes. In summary, our study results contributed to the body of knowledge showing multimorbidity was associated with excess mortality and it

also provided evidence describing the joint effects of comorbidity on mortality in the middle-aged and senior Canadian population. Further studies focusing on investigating

multimorbidity and mortality in the middle-aged Canadian population, as well as exploring other potential comorbidities associated with excess mortality, are necessary to the management of multimorbidity. More public health programs should be initiated to prevent chronic diseases and multimorbidity, which in turn, would save lives, improve

quality of life, and save healthcare dollars.

description: We report a method to determine the phase and amplitude of sinusoidally modulated event rates, binned into four bins per oscillation, based on data generated at the resonant neutron spin-echo spectrometer RESEDA. The presented algorithm relies on a reconstruction of the unknown parameters. It omits a calculation intensive fitting procedure and avoids contrast reduction due to averaging effects. It allows the current data acquisition bottleneck at RESEDA to be relaxed by a factor of four and thus increases the potential time resolution of the detector by the same factor. We explain the approach in detail and compare it to the established fitting procedures of time series having four and 16 time bins per oscillation. In addition we present the empirical estimates of the errors of the three methods and compare them to each other. We show that the reconstruction is unbiased, asymptotic, and efficient for estimating the phase. Reconstructing the contrast increases the error bars by roughly 10% as compared to fitting 16 time binned oscillations. Finally, we give heuristic, analytical equations to estimate the error for phase and contrast as a function of their initial values and counting statistics.

description: Despite their economic importance, some export-oriented cash crops inherently have low nutritional value for smallholder farmers in developing countries, where the prevalence of malnutrition and food insecurity remains alarming. This paper investigates the nutritional effects of a multi-faceted nutrition-sensitive agricultural programme, uniquely designed to address food and nutrition insecurity among smallholder cocoa, coffee and cashew farmers in Sierra Leone. Estimation of programme effects is done using the inverse-probability-weighted regression adjustment, which addresses potential selection bias on observables and accommodates multiple programme exposure. We do not find a positive effect on household and individual dietary outcomes of the production-focused component, unless it is complemented with nutrition education. The analysis shows that combining both cash crop production and nutrition interventions significantly improves household, maternal and children’s dietary diversity and, more importantly, the intake of micronutrient-rich foods among smallholder cash cropping households. This result holds after controlling for unobserved heterogeneity using the correlated random effects model. We found improvements in nutrition knowledge, and women’s confidence to be the potential pathways linking the combined intervention to better dietary outcomes.

description: A theorem of A. and C. Rényi on periodic entire functions states that an entire function $f(z) $ must be periodic if $ P(f(z)) $ is periodic, where $ P(z) $ is a non-constant polynomial. By extending this theorem, we can answer some open questions related to the conjecture of C. C. Yang concerning periodicity of entire functions. Moreover, we give more general forms for this conjecture and we prove, in particular, that $ f(z) $ is periodic if either $ P(f(z)) f^{(k)}(z) $ or $ P(f(z))/f^{(k)}(z) $ is periodic, provided that $ f(z) $ has a finite Picard exceptional value. We also investigate the periodicity of $ f(z) $ when $ f(z)^{n}+a_{1} f^{\prime}(z)+\cdots+a_{k} f^{(k)}(z) $ is periodic. In all our results, the possibilities for the period of $ f(z) $ are determined precisely.

On Applications of Multi-Armed Bandit and Bayesian Optimization Approaches for AutoML Problems
Creators: Lu, Shan
Publisher: name: University of Alberta Library
Year: 2022

Automated Machine Learning (AutoML) aims to alleviate human efforts and automate the time-consuming and iterative processes in the development of machine learning methods. In this thesis, we study two AutoML tasks: automated Data Augmentation (DA) and Hyperparameter Optimization (HPO). Automated DA searches for optimal data augmentation policies and is a widely used regularization technique for training deep neural networks. However, since early approaches, e.g., AutoAugment, cost thousands of GPU hours, there is a recent trend to investigate low-cost search methods that still yield effective augmentation policies. In this thesis, we propose a novel multi-armed bandit algorithm, named Bandit Data Augment (BDA), to efficiently search for optimal and transferable augmentation policies. We design a reward signal based on each batch training step of neural networks to reduce the evaluation cost of augmentation policies. Moreover, we propose the Evolutionary Pruning algorithm to allocate more search resources on potentially optimal operation pairs, leading to sparse selection of operation pairs and generalizable policies. Extensive experiments demonstrate that BDA can achieve comparable or better performance than previous auto-augmentation methods on a wide range of models on CIFAR-10/100, SVHN and ImageNet benchmarks.

Automated HPO algorithms search for optimal hyperparameter configurations used in machine learning and are key to boosting model performance in reality. Many previous HPO methods are based on Bayesian Optimization. However, Bayesian Optimization requires sequentially exploring many data samples to find promising configurations. In this thesis, we propose an efficient batch HPO algorithm that utilizes a combination of Bayesian Optimization and Covariance Matrix Adaptation Evolution Strategy (CMA-ES) as a hybrid sampler to sample configurations while balancing exploitation and exploration. We also propose an ensemble prediction model consisting of various surrogate models to approximate the objective function more accurately. We conduct our experiments on 20 HPO datasets from recommendation system scenarios. Our approach ranked the 4th and 7th places in the training and tournament stages of the Automated HPO Contest in QQ Brower 2021 AI Algorithm Competition at CIKM 2021 AnalytiCup, respectively.
Celestial Visions: Imagining and Engineering Spaceflight in the United States, 1899-1969
Creators: Hajramezan, Solomon
Publisher: name: University of Alberta Library
Year: 2022

Human space travel in the United States was the culmination of years of research, immense technological progress, and enormous collaborative projects, particularly in the 1950s and 1960s. It was also, as this thesis argues, a product of imagination—that is to say, a consequence of space travel’s fictional and imaginative conceptions. Science fiction stories advanced precise articulations of what spaceflight might be like and what its achievement would entail. Such tales inspired the pioneers of astronautics in the late 19th and early 20th centuries to translate these interplanetary fantasies into practical realities. In turn, these pioneers helped forge the nascent field of astronautics, and inspired generations of enthusiasts and engineers whose later efforts constituted a foundation upon which future developments were realized. In the American context, this process of imagination, inspiration, and innovation culminated most visibly with the Apollo 11 Moon landing in 1969. The origins of many of the ideational and technological antecedents to human space travel were located in a dream of spaceflight, and conveyed through various, imaginative means, whether fictional or extrapolative in nature. This dream, as I argue, led to meaningful technological developments and progress, and produced a cultural environment in the United States that was receptive to the advent of space travel. This thesis explores the rise and imaginative origins of American rocketry in the early 20th century, the development of large space boosters in the mid-20thcentury, the flourishing of space media in popular culture during the 1950s, and the influence of imaginative visual media, with a focus on the American science fiction space travel films of the 1950s and 1960s. By tracing the linkages binding sources of inspiration to their ultimate results, whether they are technological innovations or cultural phenomena, this thesis maps out “threads of imagination” that reveal the influence and effect of the cosmic imagination in the United States, and how it helped bring about spaceflight.

description: Microfinance is seen as an important vehicle for developing small businesses in developing and transitional economies despite the relative absence of supporting research. We use mixed methods to offer a nuanced empirical exploration of the relationship between microfinance and everyday entrepreneurial practice(s) in Kazakhstan. As in many transitional contexts, ‘unbankable’ borrowers here operate in a vibrant informal sector, face high degrees of uncertainty, and retain a strong distrust of a corrupt/predatory state. Our data-based methodology for analysing borrowers’ diverse relationships with microfinance organisations (MFOs) generates insights into their multiple pathways to business development. Both ‘outreac\h’ and ‘commercialised’ MFOs sustain micro-flows of resources that are critical for everyday entrepreneurs who need to finance ongoing consumption and contingencies whilst also (and by) building up their small businesses. Microfinance use did not promote formalisation or impersonalised banking relationships. Instead, MFOs focused primarily on repayment, clients’ businesses remained partially formalised or unregistered across all stages of growth and the lending relationships preferred by Private MFOs and borrowers were highly personalised. Consequently, we call for assumptions about how microfinance can (and should) drive small business development need to be rethought for transitional contexts.

description: Scalable quantum computing can become a reality with error correction, provided coherent qubits can be constructed in large arrays. The key premise is that physical errors can remain both small and sufficiently uncorrelated as devices scale, so that logical error rates can be exponentially suppressed. However, energetic impacts from cosmic rays and latent radioactivity violate both of these assumptions. An impinging particle ionizes the substrate, radiating high energy phonons that induce a burst of quasiparticles, destroying qubit coherence throughout the device. High-energy radiation has been identified as a source of error in pilot superconducting quantum devices, but lacking a measurement technique able to resolve a single event in detail, the effect on large scale algorithms and error correction in particular remains an open question. Elucidating the physics involved requires operating large numbers of qubits at the same rapid timescales as in error correction, exposing the event's evolution in time and spread in space. Here, we directly observe high-energy rays impacting a large-scale quantum processor. We introduce a rapid space and time-multiplexed measurement method and identify large bursts of quasiparticles that simultaneously and severely limit the energy coherence of all qubits, causing chip-wide failure. We track the events from their initial localised impact to high error rates across the chip. Our results provide direct insights into the scale and dynamics of these damaging error bursts in large-scale devices, and highlight the necessity of mitigation to enable quantum computing to scale.

description: Logging -- used for system events and security breaches to describe more informational yet essential aspects of software features -- is pervasive. Given the high transactionality of today's software, logging effectiveness can be reduced by information overload. Log levels help alleviate this problem by correlating a priority to logs that can be later filtered. As software evolves, however, levels of logs documenting surrounding feature implementations may also require modification as features once deemed important may have decreased in urgency and vice-versa. We present an automated approach that assists developers in evolving levels of such (feature) logs. The approach, based on mining Git histories and manipulating a degree of interest (DOI) model, transforms source code to revitalize feature log levels based on the "interestingness" of the surrounding code. Built upon JGit and Mylyn, the approach is implemented as an Eclipse IDE plug-in and evaluated on 18 Java projects with $\sim$3 million lines of code and $\sim$4K log statements. Our tool successfully analyzes 99.22% of logging statements, increases log level distributions by $\sim$20%, and increases the focus of logs in bug fix contexts $\sim$83% of the time. Moreover, pull (patch) requests were integrated into large and popular open-source projects. The results indicate that the approach is promising in assisting developers in evolving feature log levels.

Lithofacies Characteristics, Reservoir Properties, and Ichnology of the Upper Montney Member (Spathian)
Creators: Feng,Chenyang
Publisher: name: University of Alberta Library
Year: 2022

The Lower Triassic Montney Formation in west-central Alberta and northeastern British Columbia has become one of the most productive reservoirs in Western Canada over the past 15 years. It is projected that it will play a leading role in satisfying Canada’s energy requirements over the next 20 years. This study focuses on the Upper Montney Member (UMM), which is interpreted to represent the deposition within a wave- to storm-influenced, low-gradient, predominantly siliciclastic ramp setting. The lithology is dominated by the interbedding or interlamination of dolomitic, medium- to coarse-grained siltstone and bituminous, fine- to medium-grained siltstone, with subordinate dolomitic, very fine-grained sandstone locally occurring towards the UMM top. Seven lithofacies are identified in the UMM, comprising a conformable, shoaling-upward (coarsening-upward) sequence. Along with the measured porosity-permeability data, analyses of high-resolution scanning electron microscopy (SEM) and thin-section based petrography are conducted to evaluate reservoir qualities of different lithofacies. Notably, the shoreface successions of the Upper Montney are classified by the lithofacies-dependent reservoir properties using Winland porosity-permeability plots. In addition, integrating the mineralogical analyses by X-ray-diffraction (XRD) and the measured values of total organic carbon (TOC), the origin of the bitumen is investigated and the Upper Montney is inferred to be a self-sourcing reservoir system.

This work also considers some ichnological attributes of the UMM to refine an understanding of environmental conditions during reservoir deposition. To do this, the ichnology of the eastern UMM, in Alberta, is compared to more distal positions in the western MMR, In British Columbia. In Alberta, trace fossils identified mainly include Phycosiphon, Teichichnus, Planolites, Cylindrichnus and Skolithos and are consistent with somewhat impoverished trace fossil assemblages associated with proximal offshore and lower shoreface settings. In British Columbia, lack of idiomorphic ichnogenera is observed in bioturbated siltstones and sandstones: this is owing in part to a lack of grainsize variabilities of the host strata. To deal with these ichnotaxonomic problematica, five ichnofossil types (Type a, b, c, d and e) are designated and interpreted ethologically. In order to investigate the ichnological variability of the shoreface successions within the Upper Montney Member in different areas, process ichnology data (bioturbation intensity, burrow diameter, bioturbation diversity, and size-diversity index) are collected and analyzed. The distinct hydrodynamic conditions and the oxygen deficiency are interpreted to be the most significant physico-chemical stresses leading to the ichnological distributions and variability.

description: To assess patient- and physician-reported reasons for discontinuing biologic therapy among patients with severe asthma from a real-world US cohort. This retrospective analysis surveyed US physicians and their patients with severe asthma who were receiving/had previously received biologic therapy between August and December 2019. Physicians managing ≥3 patients with asthma per month completed surveys on disease management, demographics, exacerbation history, and biologic adherence for eligible patients. Patients could voluntarily complete a questionnaire, providing perceptions of their disease and treatment. 117 physicians completed case reports for 285 patients; 85 patients had discontinued biologic therapy. Physicians (n = 85) and patients (n = 64) reported patient request (28.2% and 46.9%), shortness of breath (45.9% and 23.4%), other chronic respiratory symptoms (29.4% and 10.9%), cost/reimbursement (17.7%/9.4% and 20.3%/7.8%), and exacerbations (25.9% and 10.9%) among the main reasons for biologic discontinuation. Patients who continued biologic therapy were older (mean age 47.6 years) than those who discontinued (43.8 years), and were more likely to have ≥2 exacerbations in the previous year (52.5% vs 35.3%), allergic rhinitis (70.0% vs 62.4%), or chronic rhinosinusitis (30.0% vs 12.9%). Side effects were cited as reasons by only 15.3% and 7.8% of physicians and patients, respectively. The most common reasons given for discontinuation of biologic therapy were lack of symptom control, exacerbations, cost, and patient request. These data highlight the complexity of care for this patient group and the need for ongoing, regular assessment of common challenges to biologic continuation and reasons for discontinuation, including both clinical and non-clinical factors.

description: The patriarchal kinship system in India considers sons as harbingers of prosperity and daughters as liabilities who require significant outlay of resources through their lifetimes. This social system assigns a higher value to sons and perpetuates discrimination in various forms. In this paper, instead of focusing on inferior outcomes for daughters, we provide empirical evidence of disproportionate penalties placed on long-term health outcomes of their parents. Using nationally representative data on health expenditure and outcomes for 2014, we find that a higher number of daughters are associated with increased probabilities of chronic ailment and self-reported poor health among the elderly. The effects are significantly weaker for scheduled tribes, a social group with relatively egalitarian gender norms. Also, these effects are stronger for higher quintiles of standardised number of daughters. Our findings remain robust to a variety of internal validity tests. In particular, we use a recent method that accounts for omitted variable bias to arrive at consistent estimates of bias adjusted treatment effects. Improved access to education and employment for daughters, adequate social protection and milestone-based conditional cash transfers are some ways to ameliorate this bias.

description: Inspired by a recent and ongoing debate about whether foreign direct investment (FDI) represents a blessing for or an impediment to economic, social, and political development in FDI host countries this paper addresses two issues: Does the presence of foreign investors impact the occurrence of petty corruption? If so, what are the main underlying mechanisms? Geocoding an original firm-level dataset and combining it with georeferenced household survey data, this is a first attempt to analyse whether the presence of foreign investors is associated with changes in local corruption around foreign-owned production facilities in 19 Sub-Saharan African countries. Applying an estimation strategy that explores the spatial and temporal variation in the data, we find strong and consistent evidence that the presence of foreign firms increases bribery among people living nearby. When examining two potential channels, we find no clear support that FDI-induced economic activity leads to more corruption. In contrast, the results provide evidence that FDI affects corruption via norm transmission.

description: By restricting the spatial energy transmission of an electromagnetic wave, dielectric waveguides transmit light over long distances at sustained intensity. Waveguides have been used in the microwave and optical range to maintain strong signal intensities in connection with lasers, but guiding of intense short-wavelength radiation such as x-rays has proven more cumbersome. Here we investigate theoretically how tapered x-ray waveguides can focus and guide radiation from x-ray free electron lasers. Elliptical waveguides using a cladding material with high atomic number such as platinum can maintain an x-ray intensity up to three orders of magnitude larger than in free space. This feature can be used to significantly enhance resonant interactions of x-rays, for instance driving nuclear transitions up to transient nuclear population inversion. This could be the first breakthrough in nuclear state population control. Our results anticipate the important role of tapered x-ray waveguides in the emerging field of x-ray quantum optics with nuclear transitions.

Mesh geometry models

description: We present a compact and intuitive geometry representation for technical models initially given as triangle meshes. For CADlike models the defining features often coincide with the intersection between smooth surface patches. Our algorithm therefore first segments the input model into patches of constant curvature. The intersections between these patches are encoded through Bézier curves of adaptive degree, the patches enclosed by them are encoded by their (constant) mean and Gaussian curvatures. This sparse geometry representation enables intuitive understanding and editing by manipulating either the patches' curvature values and/or the feature curves. During decoding/reconstruction we exploit remeshing and hence are independent of the underlying triangulation, such that besides the feature curve topology no additional connectivity information has to be stored. We also enforce discrete developability for patches with vanishing Gaussian curvature in order to obtain straight ruling lines.

Decentralized Schemes for Grid-Forming Inverter System Efficiency Improvement and Online-Inverter Detection
Creators: Sheykhi, Ali
Publisher: name: University of Alberta Library
Year: 2022

Parallel grid-forming (GFM) inverters are used in many modern power system applications. Therefore, improving their system efficiency is of paramount importance

for energy savings. The droop control method has been conventionally used to share

the power among inverters proportional to their power ratings. However, the droop

strategy does not guarantee an efficient power sharing especially at light loads, where

the low power demand is divided among inverters, forcing them to supply a low power

at a low efficiency according to their efficiency curve. Addressing the aforementioned

issue while maintaining the advantages of parallel inverters used in residential areas

is the focus of this thesis.

A nested-loop control system for a single-phase inverter operating in standalone

mode is introduced. The control system includes current, voltage, and harmonic

control loops, and is designed based on the linear quadratic tracking (LQT) optimal

control method. The designed controllers exhibit a satisfactory performance in tracking the reference signals and rejecting the unwanted harmonics in case of linear and

nonlinear loads. Moreover, a total harmonic distortion (THD) of 1.65% is obtained

when a nonlinear load is connected to the system.

A decentralized modified droop strategy is also proposed to improve the system

efficiency of parallel grid-forming inverters. The main idea is to control the power

sharing among the inverters such that the output power of each inverter is maintained

within a proper range with respect to the inverter efficiency curves. Hence, an optimal number of inverters supply the loads efficiently, and the unnecessary inverters do

not share any power. In contrast to the existing methods, the proposed method

does not have a single point of failure while it features modularity, flexibility, and

reliability. Additionally, the reliability of the system is enhanced by extending the

lifetime of inverters with higher power ratings which are considered as valuable assets

of the system. Furthermore, a stability verification of the system within the designed

operating range of the inverter no-load frequencies is conducted to ensure a stable

operation.

As in very-light load situations none of the inverters can operate within the proper

power range with a high efficiency, an online-inverter detection (OID) method is

proposed such that each inverter detects the online inverters and the unnecessary

inverters stop injecting power to obtain a higher system efficiency. As the proposed

OID is decentralized and modular, more inverters can be added to the system without

adjusting the settings of installed inverters. Detailed derivations, simulations, and

experimental results are presented to validate the effectiveness of the schemes.
Differential signature of the microbiome and neutrophils in the oral cavity of HIV-infected individuals

HIV infection is associated with a wide range of changes in microbial communities and immune cell components of the oral cavity. The purpose of this study was to evaluate the oral microbiome in relationship to oral neutrophils in HIV-infected compared to healthy individuals. We evaluated oral washes and saliva samples from HIV-infected individuals (n=61) and healthy controls (n=43). Using 16S-rRNA gene sequencing, we found differential -diversity using Principal Coordinate Analysis (PCoA) with Bray-Curtis distances. The -diversity analysis by Faith’s, Shannon, and observed OTUs indexes indicated that the saliva samples from HIV-infected individuals harbored significantly richer bacterial communities compared to the saliva samples from healthy individuals. Notably, we observed five species of Spirochaeta including Spirochaetaceae, Spirochaeta, Treponema, Treponema amylovorum, and Treponema azotonutricum were significantly abundant. In contrast, Helicobacter species were significantly reduced in the saliva of HIV-infected individuals. Moreover, we found a significant reduction in the frequency of oral neutrophils in the oral cavity of HIV-infected individuals, which was positively related to their CD4 T cell count. In particular, we noted a significant decline in CD44 expressing neutrophils and the intensity of CD44 expression on oral neutrophils of HIV-infected individuals. This observation was supported by the elevation of soluble CD44 in the saliva of HIV-infected individuals.

Overall, the core oral microbiome was distinguishable between HIV-infected individuals on antiretroviral therapy compared to the HIV-negative group. The observed reduction in oral neutrophils might likely be related to the low surface expression of CD44, resulting in a higher bacterial diversity and richness in HIV-infected individuals.

description: This paper examines the impact of reduced availability of hard liquor in bars on sexual crimes against women outside their homes. We construct a district level panel dataset on reported crimes and use an identification strategy that exploits a natural experiment that led to a complete crackdown on bars selling hard liquor in a state of India. Using a difference-in-differences strategy, we show that placing restrictions on alcohol sale through closure of on-premise drinking outlets that serve hard liquor reduces reported incidence of sexual assault and harassment against women but has no effect on reported rapes. We conduct placebo tests and show that the result is not driven by existing pre-trends. The result is also robust to an alternative estimation strategy using a synthetic control construction and the most conservative estimate shows a reduction in sexual assaults by 10%. These results have policy implications for regulating social drinking spaces due to their impact on women’s public safety.

description: In this article, we introduce a numerical framework for quantum tomography and entanglement quantification of three-qubit generalized Werner states. The scheme involves the single-qubit SIC-POVM, which is then generalized to perform three-qubit measurements. We introduce random errors into the scheme by imposing the Poisson noise on the measured photon counts. The precision of state estimation is quantified and presented on graphs. As a special case, we compare the efficiency of the framework for the pure three-qubit generalized Werner state and the W state. The reconstructed states are presented graphically and discussed.
