Superconducting Flux Memory for Cryogenic Applications
Gregory R. Boyd, Jeremy Clark, Mark Covington +15
We report the development of flux memory for use with superconducting circuits. This technology stores persistent currents in superconducting loops on-chip to be used to provide fl…
Fast Microwave-free State Preparation and Measurement of Superconducting Qubits
R. Abraham, F. Amet, P. Anderson +212
Fast, high-fidelity, scalable state preparation and measurement is critical to the realization of a quantum computing system. The state-of-the-art methods for preparation and reado…
Coherent Phonon Blocking in Superlattices
Anil Erol, Xiang Hua, Kirby Myers +9
At cryogenic temperatures, phonons become one of the dominant energy carriers and thus can strongly influence the performance of electronic and sensing devices. In this work, we pr…
Transmon Phase Gates Controlled by Superconducting Soliton DAC
Derek Reitz, Tony X. Zhou, Aditya Sharma +10
We introduce a superconducting digital-to-analog converter (DAC) that filters control noise, provides native multiplexing, performs quantum gates in nanoseconds, and can be control…
