A workshop was held at the EDF offices in Washington, DC, on June 15 and 16, 2022, to discuss the current state of knowledge and to define productive courses of action in better determination and source apportionment of methane emission rates, and

AI Use Taxonomy: A Human-Centered Approach

March 26, 2024
Author(s)
Mary Frances Theofanos, Yee-Yin Choong, Theodore Jensen
As artificial intelligence (AI) systems continue to be developed, humans will increasingly participate in human-AI interactions. Humans interact with AI systems to achieve particular goals. To ensure that AI systems contribute positively to human-AI

Certification Approaches for Weigh-In-Motion Systems in Law Enforcement Applications

March 26, 2024
Author(s)
Katrice Lippa, Jan Konijnenburg, Loren Minnich, Tanvi Pandya, James Willis
Every day, overweight and excessively heavy vehicles cause damage to roads, bridges, and other vehicle-based infrastructure. To protect this vital transportation infrastructure for the U.S., states have imposed weight limits for commercial and fleet

Bilayer crystals of trapped ions for quantum information processing

March 25, 2024
Author(s)
Samarth Hawalder, Prakriti Shahi, Allison Carter, Ana Maria Rey, John J. Bollinger, Athreya Shankar
Trapped ion systems are a leading platform for quantum information processing, but they are currently limited to 1D and 2D arrays, which imposes restrictions on both their scalability and their range of applications. Here, we propose a path to overcome

A case study of multi-modal, multi-institutional data management for the combinatorial materials science community

Author(s)
Sarah Allec, Eric Muckley, Nathan Johnson, Christopher Borg, Dylan Kirsch, Joshua B. Martin, Ichiro Takeuchi, Andrew Lee, James Saal, Logan Ward, Apruva Mehta
Although the convergence of high-performance computing, automation, and machine learning has significantly altered the materials design timeline, transformative advances in functional materials and acceleration of their design will require addressing the

NIST Scientific Integrity Program Annual Report

March 22, 2024
Author(s)
Anne Andrews, Justyna Zwolak
This report summarizes the findings of the National Institute of Standards and Technology Scientific Integrity Program assessment of the program for the period between 1 June 2022 and 30 September 2023. It provides an assessment of the current state of the

Clifford-Deformed Surface Codes

March 19, 2024
Author(s)
Arpit Dua, Aleksander Kubica, Liang Jiang, Steven Flammia, Michael Gullans
Kitaev's toric/surface code and its numerous variants provide promising approaches to practi- cal quantum error correction (QEC). As recently discovered, a careful choice of the code variant and lattice layout can dramatically reduce logical error rate for

Measurement-driven Langevin modeling of superparamagnetic tunnel junctions

March 19, 2024
Author(s)
Liam Pocher, Temitayo Adeyeye, Sidra Gibeault, Philippe Talatchian, Ursula Ebels, Daniel Lathrop, Jabez J. McClelland, Mark Stiles, Advait Madhavan, Matthew Daniels
Superparamagnetic tunnel junctions are important devices for a range of emerging technologies, but most existing compact models capture only their mean switching rates. Capturing qualitatively accurate analog dynamics of these devices will be important as

Precision Bounds on Continuous-Variable State Tomography Using Classical Shadows

March 18, 2024
Author(s)
Srilekha Gandhari, Victor Albert, Thomas Gerrits, Jacob Taylor, Michael Gullans
Shadow tomography is a framework for constructing succinct descriptions of quantum states, called classical shadows, with powerful methods to bound the estimators used. Classical shadows are well-studied in the discrete-variable case, which consists of
