The design and performance of an electronic torque standard directly traceable to the revised SI

May 25, 2023
Author(s)
Zane Comden, John-Edward Draganov, Stephan Schlamminger, Frank Seifert, Charles Waduwarage Perera, David B. Newell, Leon Chao
The United States National Institute of Standards and Technology (NIST) has been developing a new device for primary standard realization of torque utilizing established trace- ability to the quantum-electrical International System of Units (SI) standards

Automated extraction of capacitive coupling for quantum dot systems

May 24, 2023
Author(s)
Joshua Ziegler, Florian Luthi, Mick Ramsey, Felix Borjans, Guoji Zheng, Justyna Zwolak
Gate-defined quantum dots (QDs) have appealing attributes as a quantum computing platform. However, near-term devices possess a range of possible imperfections that need to be accounted for during the tuning and operation of QD devices. One such problem is

Predicting broadband resonator-waveguide coupling for microresonator frequency combs through fully connected and recurrent neural networks with and without attention mechanism

May 24, 2023
Author(s)
Ergun Simsek, Masoud Soroush, Gregory Moille, Kartik Srinivasan, Curtis Menyuk
Broadband microresonator frequency combs are being intensely pursued for deployable technologies like optical atomic clocks. Spectral features, such as the dispersion in their coupling to an access waveguide, are critical for engineering these devices for

Recommendations for Federal Vulnerability Disclosure Guidelines

May 24, 2023
Author(s)
Kim B. Schaffer, Peter Mell, Hung Trinh, Isabel Van Wyk
Receiving reports on suspected security vulnerabilities in information systems is one of the best ways for developers and services to become aware of issues. Formalizing actions to accept, assess, and manage vulnerability disclosure reports can help reduce

Determining Steel Weld Qualification and Performance for Hydrogen Pipelines: Phase I Report

May 23, 2023
Author(s)
Matthew Connolly, May Ling Martin, Zack Buck, Newell Moser, Enrico Lucon, Damian Lauria, Peter Bradley, Andrew Slifka, Robert Amaro
This report details the results of Phase I of the DOT/PHMSA sponsored work on "Determining Steel Weld Qualification and Performance for Hydrogen Pipelines". In this work, the goals of Phase I were 1) to perform a literature review of steel weld

Preparing for 6G: Developing best practices and standards for industrial measurements of low-loss dielectrics

May 23, 2023
Author(s)
Lucas Enright, Marzena Olszewska-Placha, Michael Hill, Say Phommakesone, Daisuke Kato, Charles Hill, Hanna Kahari, Chiawen Lee, Chang-Sheng Chen, Nate Orloff, Malgorzata Celuch, Urmi Ray
With growing interest in millimeter-wave (mmWave, 30 GHz – 300 GHz) technologies, researchers and manufacturers need standard reference materials and best practices for measurement validation, material acceptance, and quality assurance. Today, there is no

Neural-network decoders for measurement induced phase transitions

May 22, 2023
Author(s)
Hossein Dehghani, Ali Lavasani, Mohammad Hafezi, Michael Gullans
Open quantum systems have been shown to host a plethora of exotic dynamical phases. Measurement-induced entanglement phase transitions in monitored quantum systems are a striking example of this phenomena. However, naive realizations of such phase

User Perceptions and Experiences with Smart Home Updates

May 22, 2023
Author(s)
Susanne M. Furman, Julie Haney
Updates may be one of the few tools consumers have to mitigate security and privacy vulnerabilities in smart home devices. However, little research has been undertaken to understand users' perceptions and experiences with smart home updates. To address

Signal Readout for Transition-Edge Sensor X-ray Imaging Spectrometers

May 20, 2023
Author(s)
Hiroki Akamatsu, W.Bertrand (Randy) Doriese, John Mates, Brian Jackson
Arrays of low-temperature microcalorimeters provide a promising technology for X-ray astrophysics: the imaging spectrometer. A camera with at least several thousand pixels, each of which has an energy-resolving power (E∕ΔE_FWHM) of a few thousand across a

Exchange-Biased Quantum Anomalous Hall Effect

May 19, 2023
Author(s)
Peng Zhang, Purnima P. Balakrishnan, Christopher Eckberg, Peng Deng, Tomohiro Nozaki, Sukong Chong, Patrick Quarterman, Megan Holtz, Brian B. Maranville, Gang Qiu, Lei Pan, Eve Emmanouilidou, Ni Ni, Masashi Sahashi, Alexander Grutter, Kang L. Wang
The quantum anomalous Hall (QAH) effect is characterized by a dissipationless chiral edge state with a quantized Hall resistance at zero magnetic field. Manipulating the QAH state is of great importance in both the understanding of topological quantum

Nonlinear Networks for Arbitrary Optical Synthesis

May 19, 2023
Author(s)
Jennifer Black, Zachary Newman, Su-Peng Yu, David Carlson, Scott Papp
Nonlinear wavelength conversion is a powerful control of light, especially when implemented at the nanoscale with integrated photonics. However, strict energy conservation and phase-matching requirements constrain the converted output. To overcome these

Food Nutrition and Safety Measurements Quality Assurance Program: Exercise 1 Final Report

Author(s)
Colleen E. Bryan Sallee, Melissa M. Phillips, Charles Barber, Carolyn Burdette, Laura Wood, Shaun Kotoski
The Food Nutrition and Safety Measurements Quality Assurance Program (FNSQAP) was launched in 2021. FNSQAP was established to assist laboratories in the development and validation of new analytical methods, in improving the quality of their analytical

Low-Rank Gradient Descent for Memory-Efficient Training of Deep In-Memory Arrays

May 18, 2023
Author(s)
Siyuan Huang, Brian Hoskins, Matthew Daniels, Mark Stiles, Gina C. Adam
The movement of large quantities of data during the training of a Deep Neural Network presents immense challenges for machine learning workloads. To minimize this overhead, espe- cially on the movement and calculation of gradient information, we introduce
