Processing Pulses from TES Microcalorimeter X-ray Detectors

August 6, 2021
Author(s)
Terrence Jach, Stephan M. Thurgate
Microcalorimeter x-ray detectors employing a transition-edge sensor are capable of very high energy resolution, but this depends on an understanding of the readout process. The combination of thermal cooling and thermoelectric feedback present in most

Quantum-enhanced sensing of displacements and electric fields with large trapped-ion crystals

August 6, 2021
Author(s)
Kevin Gilmore, Matthew Affolter, Judith Jordan, Diego Barberena, Robert Lewis-Swan, Ana Maria Rey, John J. Bollinger
Developing the isolation and control of ultracold atomic systems to the level of single quanta has led to significant advances in quantum sensing, yet demonstrating a quantum advantage in real world applications by harnessing entanglement remains a core

Reservoir computing leveraging the transient non-linear dynamics of spin-torque nano-oscillators

August 6, 2021
Author(s)
Mathieu Riou, Jacob Torrejon, Flavio Abreu Araujo, Sumito Tsunegi, Guru Khalsa, Damien Querlioz, Paolo Bortolotti, Nathan Leroux, Danijela Markovic, Vincent Cros, K. Yakushiji, Akio Fukushima, Hitoshi Kubota, Shinji Yuasa, Mark D. Stiles, Julie Grollier
Present artificial intelligence algorithms require extensive computations to emulate the behavior of large neural networks, operating current computers near their limits, which leads to high energy costs. A possible solution to this problem is the

Resource-efficient dissipative entanglement of two trapped-ion qubits

August 6, 2021
Author(s)
Daniel Cole, Stephen Erickson, Giorgio Zarantonello, Panyu Hou, Jenny Wu, Karl Horn, Daniel Slichter, Florentin Reiter, Christiane Koch, Dietrich Leibfried
We demonstrate a simplified method for generating an entangled state of two trapped-ion qubits. Our implementation produces its target state faster and with higher fidelity than previous demonstrations of dissipative entanglement generation, while

Topological Frequency Combs and Nested Temporal Solitons

August 5, 2021
Author(s)
Sunil Mittal, Gregory Moille, Kartik Srinivasan, Yanne Chembo, Mohammad Hafezi
Recent advances in realizing optical frequency combs using nonlinear parametric processes in integrated photonic resonators have revolutionized on-chip optical clocks, spectroscopy, and multi channel optical communications. At the same time, the

Trapped electrons and ions as particle detectors

August 5, 2021
Author(s)
Jacob Taylor, Daniel Carney, Hartmut Haffner, David Moore
Electrons and ions trapped with electromagnetic fields have long served as important high- precision metrological instruments, and more recently have also been proposed as a platform for quantum information processing. Here we point out that these systems

Electrically Driven Exchange Bias via Solid State Magneto-Ionics

August 4, 2021
Author(s)
Peyton Murray, Christopher Jensen, Alberto Quintana, Junwei Zhang, Xixiang Zhang, Alexander Grutter, Brian Kirby, Kai Liu
Electrically induced ionic motion offers a new way to realize voltage-controlled magnetism, opening the door to a new generation of logic, sensor, and data storage technologies. Here, we demonstrate an effective approach to magneto-ionically and

Demonstration of a laser powder bed fusion combinatorial sample for high-throughput microstructure and indentation characterization

August 3, 2021
Author(s)
Jordan Weaver, Adam L. Pintar, Carlos R. Beauchamp, Howard Joress, Kil-Won Moon, Thien Q. Phan
High-throughput experiments that use combinatorial samples with rapid measurements can be used to provide process-structure-property information at reduced time, cost, and effort. Developing these tools and methods is essential in additive manufacturing

Exploring Government Security Awareness Programs: A Mixed-Methods Approach

August 3, 2021
Author(s)
Jody Jacobs, Julie Haney, Susanne M. Furman, Fernando Barrientos
Organizational security awareness programs are often underfunded and rely on part-time security awareness professionals who may lack sufficient background, skills, or resources necessary to manage an effective and engaging program. U.S. government

Evolution of Magnetic Interactions in Sb-Substituted MnBi 2 Te 4

August 2, 2021
Author(s)
S. Riberolles, Q. Zhang, Elijah Gordon, Nicholas Butch, Liqin Ke, J.-Q. Yan, R. McQueeney
The Mn(Bi 1−xSb x) 2Te 4 series is purported to span from antiferromagnetic (AF) topological insulator at x = 0 to a trivial AF insulator at x = 1. Here we report on neutron diffraction and inelastic neutron scattering studies of the magnetic interactions

A Novel Data Standards Platform using ISO Core Components Technical Specification

August 1, 2021
Author(s)
Nenad Ivezic, Boonserm Kulvatunyou, Elena Jelisic, Hakju Oh, Simon P. Frechette, Vijay Srinivasan
It is generally observed in inter-organizational communication that present-day data exchange standards are too costly and too complex to develop and use. These problems in data exchange are felt keenly by manufacturing industry with its vast supply chains

Design of a 3000 pixel transition-edge sensor x-ray spectrometer for microcircuit tomography

August 1, 2021
Author(s)
Paul Szypryt, Douglas Bennett, William J. Boone, Amber L. Dagel, G Dalton, William Doriese, Malcolm Durkin, Joseph Fowler, Edward Garboczi, Jonathon D. Gard, Gene Hilton, Jozsef Imrek, E S. Jimenez, Vincent Y. Kotsubo, K Larson, Zachary H. Levine, John Mates, D McArthur, Kelsey Morgan, Nathan J. Nakamura, Galen O'Neil, Nathan Ortiz, Christine G. Pappas, Carl Reintsema, Dan Schmidt, Daniel Swetz, K R. Thompson, Joel Ullom, C Walker, Joel C. Weber, Abigail Wessels, J W. Wheeler
Feature sizes in integrated circuits have decreased substantially over time, and it has become increasingly difficult to three-dimensionally image these complex circuits after fabrication. This can be important for process development, defect analysis, and

Adaptive Peak Fitting for Isotope Analysis via Atom Probe Mass Spectrometry

July 30, 2021
Author(s)
Frederick Meisenkothen, Daniel Samarov, Mark McLean, Irina Kalish, Eric B. Steel
Atom probe tomography (APT) is an emergent characterization technique that has begun to see widespread use within the last 15 years. The technique offers the highest spatial resolution of any mass spectrometry technique for solid-state specimens, as well
