Approximate joint measurements of qubit observables
Authors: Busch P. , Heinosaari T.
Published: March 2021

Joint measurements of qubit observables have recently been studied in conjunction with quantum information processing tasks such as cloning. Considerations of such joint measurements have until now been restricted to a certain class of observables that can be characterized by a form of covariance. Here we investigate conditions for the joint measurability of arbitrary pairs of qubit observables. For pairs of noncommuting sharp qubit observables, a notion of approximate joint measurement is introduced. Optimal approximate joint measurements are shown to lie in the class of covariant joint measurements. The marginal observables found to be optimal approximators are generally not among the coarse-grainings of the observables to be approximated. This yields scope for the improvement of existing joint measurement schemes. Both the quality of the approximations and the intrinsic unsharpness of the approximators are shown to be subject to Heisenberg-type uncertainty relations.
Upper bounds on the performance of differential-phase-shift quantum key distribution
Authors: Gomez-Sousa H. , Curty M.
Published: March 2021

In this paper, we investigate limitations imposed by sequential attacks on the performance of a differential-phase-shift (DPS) quantum key distribution (QKD) protocol with weak coherent pulses. Specifically, we analyze a sequential attack based on optimal unambiguous discrimination of the relative phases between consecutive signal states emitted by the source. We show that this attack can provide tighter upper bounds for the security of a DPS QKD scheme than those derived from sequential attacks where the eavesdropper aims to identify the state of each signal emitted by the source unambiguously.

Published: March 2021

We provide an introduction to the use of ion crystals in a Penning trap for experiments in quantum information. Macroscopic Penning traps allow for the containment of a few to a few million atomic ions whose internal states may be used in quantum information experiments. Ions are laser Doppler cooled, and the mutual Coulomb repulsion of the ions leads to the formation of crystalline arrays. The structure and dimensionality of the resulting ion crystals may be tuned using a combination of control laser beams and external potentials. We discuss the use of two-dimensional $^{9}$Be$^{+}$ ion crystals for experimental tests of quantum control techniques. Our primary qubit is the 124 GHz ground-state electron spin flip transition, which we drive using microwaves. An ion crystal represents a spatial ensemble of qubits, but the effects of inhomogeneities across a typical crystal are small, and as such we treat the ensemble as a single effective spin. We are able to initialize the qubits in a simple state and perform a projective measurement on the system. We demonstrate full control of the qubit Bloch vector, performing arbitrary high-fidelity rotations ($\tau_{\pi}\sim$200 $\mu$s). Randomized Benchmarking demonstrates an error per gate (a Pauli-randomized $\pi/2$ and $\pi$ pulse pair) of $8\pm1\times10^{-4}$. Ramsey interferometry and spin-locking measurements are used to elucidate the limits of qubit coherence in the system, yielding a typical free-induction decay coherence time of $T_{2}\sim$2 ms, and a limiting $T_{1\rho}\sim$688 ms. These experimental specifications make ion crystals in a Penning trap ideal candidates for novel experiments in quantum control. As such, we briefly describe recent efforts aimed at studying the error-suppressing capabilities of dynamical decoupling pulse sequences, demonstrating an ability to extend qubit coherence and suppress phase errors. We conclude with a discussion of future avenues for experimental exploration, including the use of additional nuclear-spin-flip transitions for effective multiqubit protocols, and the potential for Coulomb crystals to form a useful testbed for studies of large-scale entanglement.
On global effects caused by locally noneffective unitary operations
Authors: Gharibian S. , Kampermann H. , Bruss D.
Published: March 2021

Given a bipartite quantum state $\rho$ with subsystems $A$ and $B$ of arbitrary dimensions, we study the entanglement detecting capabilities of locally noneffective, or cyclic, unitary operations [Fu, Europhys. Lett., vol. 75]. Local cyclic unitaries have the special property that they leave their target subsystem invariant. We investigate the distance between $\rho$ and the global state after local application of such unitaries as a possible indicator of entanglement. To this end, we derive and discuss closed formulae for the maximal such distance achievable for three cases of interest: (pseudo)pure quantum states, Werner states, and two-qubit states. What makes this criterion interesting, as we show here, is that it surprisingly displays behavior similar to recent anomalies observed for non-locality measures in higher dimensions, as well as demonstrates an equivalence to the CHSH inequality for certain classes of two-qubit states. Yet, despite these similarities, the criterion is not itself a non-locality measure. We also consider entanglement detection in bound entangled states.
Quantum universality by state distillation
Authors: Reichardt B.W.
Published: March 2021

Quantum universality can be achieved using classically controlled stabilizer operations and repeated preparation of certain ancilla states. Which ancilla states suffice for universality? This ``magic states distillation" question is closely related to quantum fault tolerance. Lower bounds on the noise tolerable on the ancilla help give lower bounds on the tolerable noise rate threshold for fault-tolerant computation. Upper bounds show the limits of threshold upper-bound arguments based on the Gottesman-Knill theorem. We extend the range of single-qubit mixed states that are known to give universality, by using a simple parity-checking operation. For applications to proving threshold lower bounds, certain practical stability characteristics are often required, and we also show a stable distillation procedure.}{No distillation upper bounds are known beyond those given by the Gottesman-Knill theorem. One might ask whether distillation upper bounds reduce to upper bounds for single-qubit ancilla states. For multi-qubit pure states and previously considered two-qubit ancilla states, the answer is yes. However, we exhibit two-qubit mixed states that are not mixtures of stabilizer states, but for which every postselected stabilizer reduction from two qubits to one outputs a mixture of stabilizer states. Distilling such states would require true multi-qubit state distillation methods.
Ensemble Effects of Explicit Solvation on Allylic Oxidation
Authors: Le Hung , Guagliardo Mariano , Gorden Anne , Clark Aurora
Published: March 2021

Umbrella-sampling density functional theory molecular dynamics (DFT-MD) has been employed to study the full catalytic cycle of the allylic oxidation of cyclohexene using a Cu(II) 7-amino-6-((2-hydroxybenzylidene)amino)quinoxalin-2-ol complex in acetonitrile to create cyclohexenone and H$_2$O as products. In comparison to gas-phase DFT, the solvent effect is observed as the rate determining allylic H-atom abstraction step has a free energy barrier of 12.1 $\pm$ 0.2 kcal/mol in solution. During the cycle, the explicit solvation and ensemble sampling of solvent configurations reveals important dehydrogenation and re-hydrogenation steps of the -NH$_2$ group bound to the Cu-site that are essential to catalyst recovery. This work illustrates the importance of ensemble solvent configurational sampling to reveal the breadth of processes that underpin the full catalytic cycle.

Published: March 2021

Current guidance by leading public health agencies recommends wearing a 3-layer cloth-based face mask with a middle non-woven material insert to reduce the transmission of infectious respiratory viruses like SARS-CoV-2. In this work we explore the material characteristics for a range of readily available non-woven materials and their sub-micron particle filtration efficiency (PFE), with the aim of providing evidence-based guidelines for selecting appropriate materials as inserts in cloth-based masks. We observed a wide range of ideal PFE for the tested non-woven materials, with polypropylene, Swiffer and Rayon/polyester blend providing the highest PFE and breathability. Our results suggest that materials comprising loose 3D fibrous webs (e.g. flannel, Swiffer and gauze) exhibited enhanced filtration efficiency compared to compressed counterparts. Common modifications to fabrics, such as water-resistant treatment and a sewn seam were also investigated. Overall, we demonstrate that adding an appropriate non-woven material as an insert filter can significantly improve the performance of cloth-based masks, and there exist suitable cellulose-based alternatives to polypropylene.

As the price of renewable electricity continues to plummet, hydrogen (H2) production via water electrolysis is gaining momentum globally as a route to decarbonize our energy systems. The requirement of high purity water for electrolysis as well as the widespread availability of seawater have led significant research efforts in developing direct seawater electrolysis technology for H2 production. In this Perspective, we critically assess the broad-brush arguments on the research and development (R&D) needs for direct seawater electrolysis from energy, cost and environmental aspects. We focus in particular on a process consisting of sea water reverse osmosis (SWRO) coupled to proton exchange membrane (PEM) electrolysis. Our analysis reveals there are limited economic and environmental incentives of pursuing R&D on today’s nascent direct seawater electrolysis technology. As commercial water electrolysis requires significant amount of energy compared to SWRO, the capital and operating costs of SWRO are found to be negligible. This leads to an insignificant increase in levelized cost of H2 (<0.1 $/kg H2) and CO2 emissions (<0.1%) from a SWRO-PEM coupled process. Our analysis poses the questions: what is the future promise of direct seawater electrolysis? With an urgent need to decarbonize our energy systems, should we consider realigning our research investments? We conclude with a forward-looking perspective on future R&D priorities in desalination and electrolysis technologies.

Authors: Turcani Lukas , Tarzia Andrew , Szczypiński Filip , Jelfs Kim
Published: March 2021

Computational software workflows are emerging as all-in-one solutions to speed up the discovery of new materials.Many computational approaches require the generation of realistic structural models for property prediction and candidate screening. However, molecular and supramolecular materials represent classes of materials with many potential applications for which there is no go-to database of existing structures or general protocol for generating structures. Here, we report a new version of the supramolecular toolkit, stk, an open-source, extendable and modular Python framework for general structure generation of (supra)molecular structures. Our construction approach follows a bottom-up process and minimises the input required from the user, making stk user-friendly and applicable to many material classes. This version of stk includes metal-containing structures and rotaxanes as well as general implementation and interface improvements. Additionally, this version includes built-in tools for exploring chemical space with an evolutionary algorithm and tools for database generation and visualisation. The latest version of stk is freely available at github.com/lukasturcani/stk

За допомогою психоаналітичних словників та енциклопедій наведений змістовий складник основних понять зазначеної проблематики. Особливе значення приділено трактуванню архетипної символіки саме психоаналітиками – З. Фрейдом та К. Юнгом. Наголошено на механізмах символізації, які були виділені З. Фрейдом у процесі аналізу сновидінь та уточнені академіком Т.С. Яценко (згущення, зміщення, натяк, локалізація, генералізація, маскування кількістю, від супротивного, гіперболізація, мінімізація, схематизація в контексті психодинамічного розуміння психіки). Розкрито можливості аналізу психомалюнків за методом активного соціально-психологічного пізнання, зокрема завдяки єдності свідомого та несвідомого компонентів психіки в процесі малювання, веденню діалогічної взаємодії психолога і респондента, спонтанності та невимушеності психокорекційного процесу, універсальності архетипної символіки.

Authors:   Timirâzevskaâ selʹskohozâjstvennaâ akademiâ, Solomin I.A.
Published: March 2021

The study of methods and technologies for waste management of production and consumption allows students studying in the direction 20.03.02 nature management and water use to become highly qualified specialists in the field of rational use of natural resources and engineering protection of the environment from generated waste. Recently, legislative and executive initiatives in the field of waste management are aimed at increasing the volume of utilization of secondary material resources from production and consumption waste. But mainly these initiatives are aimed at utilization of highly liquid waste, mainly in the form of a limited range of secondary material resources, which, on average, make up no more than one third of the use of all waste. Textile waste has received little attention in the large-scale processing industry, although the textile and clothing industry is one of the largest and fastest growing sectors in the global industry, driven by an increase in population, increased consumption, a variety of textile uses and greater productivity in mass production processes. Also, the textile industry is both the largest consumer of natural resources and the generator of production and consumption waste, which is practically not utilized, but goes to disposal facilities. This article presents the main directions for the involvement of textile waste in the general domestic system of production and consumption waste management.

For the pre-revolutionary Don historiography, complaints about the lack of a full-fledged generalizing work of the history of the Cossacks were extremely characteristic. As shown in the article, a similar situation is observed in our time: the article has again become the main genre of Cossack historiography, and the understanding of a huge number of publications on the history of various Cossack troops is extremely difficult. The author proves that in these conditions, works that claim to generalize become especially important, but it is extremely difficult to summarize all the facts, developments and research concepts on any broad topic of Cossack history. In his opinion, the search for other methods of scientific generalization and perception by historians of the developments of their colleagues looks promising. One of these ways he sees the organization of round tables on specifically Cossack topics, especially dedicated to new discoveries.

The possibilities of using distance learning on the Internet are considered with the fulfillment of the requirements of the Federal State Educational Standard of Higher Professional Education to the learning out-comes according to the indicators established in the discipline programs - to know, be able, and have skills. It is noted that distance learning, being accessible to users, does not have an evidence base for its effectiveness in ensuring the quality of education. In universities with a technological focus, the creation of an educational environment that meets the established requirements is impossible with distance learning. As an additional educational resource, it can be used in organizing students' independent work, studying optional courses, in DPO centers (retraining, professional development).

PRICE OF COSSACKS' BLOOD: IN THE PUBLISHING HOUSE OF SFU IN ROSTOV-ON-DON A.YU. PERETYATKO PUBLISHED THE ORIGINAL COLLECTION OF DOCUMENTS ON THE HISTORY OF THE DON COSSACKS
Authors:   Timirâzevskaâ selʹskohozâjstvennaâ akademiâ, Yurchenko I.Yu.
Published: March 2021

The article is devoted to the latest original documentary research of the historian Artyom Yuryevich Peretyatko, presented in a large three-volume edition at the Southern Federal University in Rostov-on-Don. The publication of new archival documents on the history of the Don Cossacks is of great interest to specialists - historians of the Cossacks. The newly discovered sources introduced into the scientific circulation make it possible to re-evaluate the history of the Cossacks in the period of the "Great Reforms" of Alexander II and "Counter-Reforms" of Alexander III. Previously, this period in the history of the Cossacks was not given sufficient attention. Three-volume A.Yu. Peretyatko filled the existing gap in the published sources on the history of the Cossacks in the second half of the 19th century. The innovative format of the publication of sources integrated with the lengthy reasoning of the author of the publication, both of a historical and source study nature, is of undoubted historiographical and bibliographic interest. However, such an original approach of the author to the academic publication of documents can cause justified criticism, both by conservative historians and source researchers and historiographers. But, despite the potential criticism of specialists, one cannot but welcome the innovative search of A.Yu. Peretyatko. It is a topical form of presenting such conservative academic work as the publication of a commented collection of archival documents. In the article, the author included a detailed own historiographic review and a short bibliography of publications on the research topic by Peretyatko.
Doing remote systemic psychotherapy during a pandemic
Authors: Helps Sarah L
Published: March 2021

This paper describes some findings from a rapid quality improvement project exploring clinician views about the delivery of remote systemic psychotherapy since the Covid-19 induced UK lockdown. Remote systemic psychotherapy is a practice response based on the need to remain physically distant from people and involves "meeting" via video link rather than in person. Written responses were gathered from early-adopter clinicians in one UK NHS trust, reflecting on their experiences of convening remote systemic psychotherapy sessions during March and April 2020. Overall, findings suggest that that remote systemic psychotherapy has been acceptable, effective and indeed welcomed by clinicians, within the pandemic context. Using a diffractive thematic analysis, four themes were constructed from clinician responses: practical and boundary issues need careful attention; the conversational flow of remote systemic psychotherapy sessions is different to that during in-person sessions; it is necessary to do things differently with words and bodies; the practice of creating meaningful dialogical communication when separated by screens is hard. Tentative practice recommendations are provided.
Reflections on the results of a roundtable on creative methods in disabilities research

Published: March 2021

In these research notes, we present the results of a roundtable and a subsequent process of reflection on the challenges facing researchers in disability studies using creative methods. The roundtable took place at a conference on disability, “Diversity & Belonging: Celebrating Difference” in Athens in 2018. The aim of the roundtable was to explore with other researchers in disability studies the challenges and joys of academic research using creative research methods. Even though the commitment to inclusive research is common in disability studies, the use of creative research methods still feels like pioneering and unconventional. The purpose of the roundtable was to discuss how we can extend the use of creative research methods so that more people can join in research work.  In these research notes, we discuss some reflections on the material that came out of our roundtable and from the reflective session we held after the roundtable. From studying these conversations, we identified four insights on the use of creative methods in disability studies: embodiment, discomfort, connection and plurality of voices.
 
Samenvatting
In deze research notes presenteren we de resultaten van een roundtable en het daaropvolgend proces van reflectie over de uitdagingen van het toepassen van creatieve onderzoeksmethoden in disability studies. De roundtable vond plaats op het disability-gerelateerd congres “Diversity & Belonging: Celebrating Difference” in Athene, 2018. Het doel van de roundtable was om samen met andere onderzoekers in disability studies de obstakels en kansen van creatieve onderzoeksmethoden in academisch onderzoek te verkennen. Hoewel onderzoek steeds meer inclusief vormgegeven wordt voelt het gebruik van creatieve methodes nog steeds aan als pionieren, baanbrekend en onconventioneel.  Het doel van de roundtable was om met andere onderzoekers samen te exploreren hoe we het gebruik van creatieve onderzoeksmethoden kunnen uitbreiden zodat meer mensen kunnen meedoen in onderzoek. In het artikel gaan we in op de resultaten van de roundtable en ons reflectieproces daarna. Door deze gesprekken te bestuderen, identificeerden we vier inzichten over het gebruik van creatieve methoden in disability studies onderzoek: rond embodiment, ongemak, verbinding en meervoudigheid van stemmen.
Invitations to mutual learning: Reflections on co-researching a social prescribing model of care during the COVID 19 pandemic
Authors: Salter Leah
Published: March 2021

This paper offers some reflections on the creative and ethical approaches to participant inclusion in a research project which is currently taking place in the time of the COVID 19 pandemic. The project is based in the county of Bridgend, South Wales, UK. An account of one of the storytelling projects this paper refers to was published in the last edition of Murmurations (Salter, 2020).
These reflections focus on the early invitation to intervention phase of the research that might traditionally be thought of as the recruitment phase, followed by interview-conversations with participants. The language of recruitment and interviewing suggests or assumes that the researcher goes in blindly and coldly with some kind of promotional campaign to find people they previously did not know and then co-opt them into a study where they are the participant or the object of study. In relational, practice-based research such as the one featured here, this does not reflect the ethics of systemic values nor community-based practice. This paper describes an alternative model to think about co-inquiry as an invitation to mutual learning. The method and the ethics of inquiry are spotlighted in this paper, within an overview of the context to inquiry - that of researching a social prescribing model of care. The paper also offers a brief reflection on learning in this early stage with contributions from co-researchers.

Gestão de Risco no Turismo.
Authors: Mariano da Rocha Marcelo , Aurélio T. da Silveira Marcos
Published: March 2021

Em muitos países destinos turísticos têm sido atingidos por eventos extremos associados às mudanças climáticas. Estas mudanças climáticas também estão relacionadas aos desastres naturais (como seca, inundações, ciclones e incêndios), cada vez mais constantes em muitas regiões. Isto tem contribuído para a incorporação da problemática da vulnerabilidade a desastres naturais nas discussões do planejamento e gestão do turismo em todas as escalas espaciais, sobretudo, em escala local. Todavia, no Brasil em particular, nas ações de planejamento e gestão de destinos turísticos, pouco tem sido considerada por parte dos formuladores de políticas públicas as consequências dos eventos extremos sobre a dinâmica do desenvolvimento turístico, como é o caso dos desastres naturais. Neste sentido, este trabalho tem como objetivo analisar os municípios no Brasil categorizados pelo Ministério do Turismo – MTUR – como destinos e, que apresentam vulnerabilidade a desastres naturais. A análise metodológica foi feita a partir do cruzamento de dados do MTUR, do Plano Nacional de Turismo (2018-2022), associados com dados da Base Territorial Estatística de Áreas de Risco – BATER, metodologia de mapeamento desenvolvida por Assis Dias (et al., 2018), pesquisadores do Centro Nacional de Monitoramento e Alertas de Desastres Naturais- CEMADEM. Os resultados demonstram que um número de municípios categorizados como destinos turísticos no Brasil apresenta vulnerabilidade a riscos de desastres naturais. Todavia, verifica-se que nas políticas públicas de turismo não estão contempladas nas suas diretrizes ações estratégicas da gestão de riscos a desastres naturais para o setor de turismo.
O discípulo (Furtado) e o mestre (Prebisch), a inversão dos papéis
Authors: Medeiros Fágner João Maia
Published: March 2021

A relação entre o discípulo Celso Furtado e o mestre Raúl Prebisch originou nos primórdios da escola da CEPAL e modificou-se a cada decênio. Nesse artigo, analisamos a trajetória desses autores a partir de três distintos momentos que correspondem às décadas de 1950, 1960 e 1970. Em cada um dos momentos, discutimos os diferentes encontros desses autores, associando-lhes às suas respectivas produções teóricas e à conjuntura latino-americana. Por resultado, no último decênio revelamos como a relações mestre-discípulo se inverteu, tornando o mestre Prebisch um leitor e seguidor das doutrinas do discípulo Furtado.
