Four terminal-pair measurements of ceramic capacitors

June 28, 2024
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

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

Author(s)
Yuhao Li, Sidi Zhao, Rahul Prasanna Misra, Chenxing Liang, Alice Judith Gillen, jobaer abdullah, Ted Laurence, Jeffrey Fagan, Narayana Aluru, Daniel Blankschtein, Aleksandr Noy
Nanofluidic channels impose extreme confinement on water and ions, giving rise to unusual transport phenomena that strongly depend on the interactions at the channel-wall interface. Yet, the questions of how the electronic properties of the nanofluidic

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

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

Cannabis Laboratory Quality Assurance Program: Exercise 2 Cannabinoid Final Report
