Due to their interesting physical properties, myriad operational regimes, small size, and industrial fabrication maturity, magnetic tunnel junctions are uniquely suited for unlocking novel computing schemes for in-hardware neuromorphic computing. In this

Polymer Identification of Floating Derelict Fishing Gear from O'ahu, Hawai`i

September 28, 2023
Author(s)
Raquel Corniuk, Katherine Shaw, Andrew McWhirter, Harry Lynch, Sarah-Jeanne Royer, Jennifer Lynch
Discarded fishing gear (DFG) comprises most of the plastic in the North Pacific Ocean and causes environmental and economic losses. Building evidence on the material construction of fishing gear types is critical to develop solutions to reduce DFG amounts

Tuning Arrays with Rays: Physics-Informed Tuning of Quantum Dot Charge States

September 28, 2023
Author(s)
Joshua Ziegler, Florian Luthi, Mick Ramsey, Felix Borjans, Guoji Zheng, Justyna Zwolak
Quantum computers based on gate-defined quantum dots (QDs) are expected to scale. However, as the number of qubits increases, the burden of manually calibrating these systems becomes unreasonable and autonomous tuning must be used. There has been a range

Electro-Optic Imaging Millimeter-Wave Propagation On-Wafer
