Author(s)
Stephan Schlamminger, Yicheng Wang, Andrew Koffman, Jordan Love
Expanding on our previous work on four terminal-pair air capacitors, we present a model for the frequency-dependent capacitance of ceramic capacitors for values ranging from 10 nF to 10 uF. Two measurements are necessary for the complete model. First, the

Global Community Technology Challenge (GCTC) Strategic Plan 2024-2026

Michael Dunaway, Thomas Roth, Edward Griffor, David A. Wollman
This document provides a strategy and a project plan for the Global Community Technology Challenge, a federal smart cities program led by the Smart Connected Systems Division at the National Institute of Standards and Technology, an agency of the U.S

Perfect cheating is impossible for single-qubit position verification

June 28, 2024
Author(s)
Carl A. Miller, Yusuf Alnawakhtha
In quantum position verification, a prover certifies her location by performing a quantum computation and returning the results (at the speed of light) to a set of trusted verifiers. One of the very first protocols for quantum position verification was

Single-Phase L10-Ordered High Entropy Thin Films with High Magnetic Anisotropy

June 28, 2024
Author(s)
Willie Beeson, Dinesh Bista, Huairuo Zhang, Sergiy Krylyuk, Albert Davydov, Gen Yin, Kai Liu
The vast high entropy alloy (HEA) composition space is promising for discovery of new material phases with unique properties. We explore the potential to achieve high magnetic anisotropy materials in single-phase HEA thin films. Thin films of FeCoNiMnCu

Leveraging Combinatorial Coverage in the Machine Learning Product Lifecycle

June 27, 2024
Author(s)
Jaganmohan Chandrasekaran, erin lanus, tyler cody, laura freeman, Raghu N. Kacker, M S Raunak, D. Richard Kuhn
The data-intensive nature of machine learning (ML)-enabled systems introduces unique challenges in test and evaluation. We present an overview of combinatorial coverage, exploring its applications across the ML-enabled system lifecycle and its potential to

Exact and approximate fluxonium array modes

June 26, 2024
Author(s)
Stephen Sorokanich, Neill Warrington, Max Hays
We present an exact solution for the array modes of fluxonium. This solution holds for arrays of any length and ground capacitance. Array mode energies are determined by convex combinations of Chebyshev polynomials and their spatial profiles are plane

Measuring the Exploitation of Weaknesses in the Wild

June 26, 2024
Author(s)
Peter Mell, Irena Bojanova, Carlos Eduardo Cardoso Galhardo
Identifying the software weaknesses exploited by attacks supports efforts to reduce developer introduction of vulnerabilities and to guide security code review efforts. A weakness is a bug or fault type that can be exploited through an operation that

A Distributed Theory for Contactless Interconnects at Terahertz Frequencies

June 25, 2024
Author(s)
Nicholas Jungwirth, Bryan Bosworth, Aaron Hagerstrom, Meagan Papac, Eric Marksz, JEROME CHERON, Kassiopeia Smith, Angela Stelson, Ari Feldman, Dylan Williams, Nathan Orloff, Christian Long
Here we test a multimodal model for distributed contactless interconnects by comparing it to 3D full-wave simulations. In comparison to 3D simulations, the model offers insight into how the interconnect works and reduces the computational cost of
