Coherence-limited digital control of a superconducting qubit using a Josephson pulse generator at 3 K

Most data generated are averaged heterodyne IQ voltages of a reflectometry of a superconducting cavity dispersively coupled to a transmon qubit, where the phase shift of the cavity probe tone is used to infer the qubit state. These data are collected while performing various parameter sweeps to track the qubit state evolution in response to various stimuli.There is also simulation data used to model qubit state evolution when driven with digital pulses.

Quantifying the Effect of Guest Binding on Host Environment Associated Data

S-parameter,  Matlab Analysis files for "Quantifying the Effect of Guest Binding on Host Environment Associated Data"Abstract:The environment around a host-guest complex is defined by of intermolecular interactions between solvent molecules and counter ions. These interactions govern both the solubility of these complexes and the rates of reactions confined within them11. Such noncovalent2 interactions between solvent molecules and ions are challenging to detect by standard analytical chemistry techniques. We use microwave microfluidic spectroscopy to quantify the hydration and ion pairing of a FeII4L4 coordination cage with a set of guest molecules having widely varying physicochemical properties3,4. Significantly, we observed that the environment around a host-guest complex changes depending on the identity of the encapsulated guest. The impact of different guest properties on host ion pairing and hydration was determined through microwave microfluidic measurements paired with principal component analysis. This analysis showed that introducing guest molecules into solution displaced counterions that were bound to the cage, and the water solubility of the guest has the greatest impact on the solvent and ion-pairing dynamics surrounding the host. We also observed that cage-counterion pairing is well-described by a single ion-pairing type, with a one-step reaction model independent of the type of cargo, and that the ion-pairing association constant is reduced for cargo with higher water solubility. Looking beyond this study, microwave microfluidics elucidates structure-property relationships that connect the host interior cavity to its external environment, and these measurements enable improved design of host-guest systems for chemical separations, catalysis, and more.

Maxwell-Bloch Equations for Two-Level System

The Maxwell-Bloch equations for a two-level system are solved in a particular case.  The example follows that of P. Siddons, "Light propagation through atomic vapours," Journal of Physics B: Atomic, Molecular, and Optical Physics 47, 093001 (2014).  In the reference, the optical intensity, population of the upper state and coherence are given for light with a carrier frequency which is on resonance.  Here, the same example is worked, but the result is given at intermediate times as well as at the entrance and exit faces as in the example.   The solution is found using Mathematica's NDSolve for the time dimension and the Method of Lines for propagation in space.

Data for "On-grid compressive sampling for spherical field measurements in acoustics" in The Journal of the Acoustical Society of America.

This dataset contains CSV files for the figures in the paper titled "On-grid compressive sampling for spherical field measurements in acoustics" in The Journal of the Acoustical Society of America. In this paper, we derive a compressive sampling method for spherical harmonic/spherical wavefunction or Wigner D-function series with sparse coefficients. Applications of these sparse expansions include spherical field measurements in acoustics and spherical near-field antenna measurements, to name a couple. The figures that this dataset is for are examples demonstrating the following: example acoustic field coefficients in the spherical harmonic/spherical wavefunction basis; relationships between spherical harmonic/spherical wavefunction/Wigner D-function coefficient sparsity and spatial Fourier coefficient sparsity; example compressive sampling reconstruction using our proposed compressive sampling method with and without noise; and comparisons between classical Nyquist sampling and our proposed compressive sampling method.

Phase-Resolved Rydberg Atom Field Sensing using Quantum Interferometry

Although Rydberg atom-based electric field sensing provides key advantages over traditional antenna-based detection, it remains limited by the need for a local oscillator (LO) for low-field and phase resolved detection. In this work, we demonstrate the general applicability of closed-loop quantum interferometric schemes for Rydberg field sensing, which eliminate the need for an LO. We reveal that the quantum-interferometrically defined phase and frequency of our scheme provides an internal reference that enables LO-free full 360 degree-resolved phase sensitivity. This internal reference can further be used analogously to a traditional LO for atom-based down-mixing to an intermediate frequency for lock-in-based phase detection, which we demonstrate by demodulating a four phase-state signal broadcast on the atoms.

NIST Fingerprint Image Registration Library (NFRL). Registers a pair of fingerprint images using two pairs of control-points (pixel locations).  Registration is rigid; translation and rotation are performed without scaling.

NFRL registers two fingerprint images based on a pair of corresponding control-points. It uses this control-pointpair of pixel locations within the images to translate and rotate the Moving image to the Fixed image.Runtime configuration parameters include:* moving and fixed image data in 8-bits-per-pixel grayscale (preferable but not required)* two-pairs of corresponding control points (pixel coordinates).The fingerprint-image rigid-registration process is performed in two steps:1. Translation of the Moving image to the Fixed image using the "first" pair of control-points (the unconstrained pair)2. Rotation of the Moving image around the Fixed image control-point (the translation "target" location) based on theangle-difference determined by the "second" pair of control-points (the constrained pair).Both final images, a few interim images, and registration metadata generated during the registration processare made available to the using software:* Final registered Moving image* Final registered Fixed image* Registered, padded, overlaid image (colorized)* Registered, padded, Moving image (grayscale)* Padded, Fixed image (grayscale)* Summed, registered, dilated overlaid image (the "blob")* Process metadata available in both text and XML format.The two Final images are registered.  They are cropped to the region-of-interest that is the smallest area of "overlap"per the registration.  Therefore, these two images have identical width and height which enables analysis using metricslike PSNR (Peak Signal to Noise Ratio).

Data for "Distributed contactless interconnects for millimeter-wave heterogeneous integration"

Included here are figures and other relevant data from the paper "Distributed contactless interconnects for millimeter-wave heterogeneous integration", submitted to TMTT Letters. Abstract: State-of-the-art integrated circuits leverage dissimilar materials to optimize system performance. Such heterogeneous integration often involves multiple chips electrically coupled to one another via bump bonds or wire-bond interconnects. While these interconnects are a mature technology for low-frequency operation (< 100 GHz), they have stringent fabrication requirements and are prone to failure during operation in the terahertz range (300 GHz to 10 THz). Next-generation integrated circuits require alternative interconnect topologies that are less sensitive to fabrication tolerances and conditions, are more robust, and have superior high-frequency performance. Here, we demonstrate distributed coupling to 325 GHz between broadside-coupled coplanar waveguides without bump bonds, wire bonds, or direct metal-to-metal bonding. The insertion loss of these contactless interconnects was approximately 1.4 dB at the maximum in the passbands at 63 GHz, 93 GHz, and 120 GHz. This interconnect topology enables robust integration of low-cost silicon with high-speed compound semiconductors for terahertz communications networks to improve reliability and increase yield.

Segmentation of lipid nanoparticles from cryogenic electron microscopy images

Lipid nanoparticles (LNPs) were prepared as described (https://doi.org/10.1038/s42003-021-02441-2) using the lipids DLin-KC2-DMA, DSPC, cholesterol, and PEG-DMG2000 at mol ratios of 50:10:38.5:1.5. Four sample types were prepared: LNPs in the presence and absence of RNA, and with LNPs ejected into pH 4 and pH 7.4 buffer after microfluidic assembly. To prepare samples for imaging, 3 ?L of LNP formulation was applied to holey carbon grids (Quantifoil, R3.5/1, 200 mesh copper). Grids were then incubated for 30 s at 298 K and 100% humidity before blotting and plunge-freezing into liquid ethane using a Vitrobot Mark IV (Thermo Fisher Scientific). Grids were imaged at 200 kV using a Talos Arctica system equipped with a Falcon 3EC detector (Thermo Fisher Scientific). A nominal magnification of 45,000x was used, corresponding to images with a pixel count of 4096x4096 and a calibrated pixel spacing of 0.223 nm. Micrographs were collected as dose-fractionated ?movies? at nominal defocus values between -1 and -3 ?m, with 10 s total exposures consisting of 66 frames with a total electron dose of 12,000 electrons per square nanometer. Movies were motion-corrected using MotionCor2 (https://doi.org/10.1038/nmeth.4193), resulting in flattened micrographs suitable for downstream particle segmentation. A total of 38 images were manually segmented into particle and non-particle regions. Segmentation masks and their corresponding images are deposited in this data set.

Dataset: An Inter-Laboratory Study of Zn-Sn-Ti-O Thin Films using High-throughput Experimental Methods

The open dataset accompanying An Inter-Laboratory Study of Zn-Sn-Ti-O Thin Films using High-throughput Experimental Methods (https://pubs.acs.org/doi/10.1021/acscombsci.8b00158).High-throughput experimental (HTE) techniques are an increasingly important way to accelerate the rate of materials research and development for many technological applications. However, there are very few publications on the reproducibility of the HTE results obtained across different laboratories for the same materials system, and on the associated sample and data exchange standards. Here, we report a comparative study of Zn-Sn-Ti-O thin films materials using high-throughput experimental methods at National Institute of Standards and Technology (NIST) and National Renewable Energy Laboratory (NREL). The thin film sample libraries were synthesized by combinatorial physical vapor deposition (co-sputtering and pulsed laser deposition), and characterized by spatially-resolved techniques for composition, structure, thickness, optical and electrical properties. The results of this study indicate that all these measurement techniques performed at two different laboratories show excellent qualitative agreement. The quantitative similarities and differences vary by measurement type, with 95% confidence interval of 0.1-0.2 eV for the band gap, 24-29 nm for film thickness, and 0.08 to 0.37 orders of magnitude for sheet resistance. Overall, this work serves as a case study for the feasibility of a High-Throughput Experimental Materials Collaboratory (HTE-MC) by demonstrating the exchange of high-throughput sample libraries, workflows and data.
