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…
Cosm: orchestrated collective dynamics give rise to rapid computational search at the solution frontier
Kenneth M. Zick, Nikhil Shukla, Alexander Marakov
We introduce Collective Switched Motion (Cosm), a heuristic optimization framework based on orchestrated collective dynamics. Cosm organizes the objective into conflict-minimized s…
High-Temporal-Resolution Measurements of the Impacts of Ionizing Radiation on Superconducting Qubits
Jihee Yang, Thomas J. Carroll, Philip Mason +19
We measure the effect of ionizing radiation on superconducting qubits with a timing resolution of 1 using microwave kinetic inductance detectors (MKIDs) fabricated on the same…
Fast, Lifetime-Preserving Readout for High-Coherence Quantum Annealers
Jeffrey A. Grover, James I. Basham, Alexander Marakov +15
We demonstrate, for the first time, that a quantum flux parametron (QFP) is capable of acting as both isolator and amplifier in the readout circuit of a capacitively shunted flux q…
High Saturation Power Josephson Parametric Amplifier with GHz Bandwidth
O. Naaman, D. G. Ferguson, R. J. Epstein
We present design and simulation of a Josephson parametric amplifier with bandwidth exceeding 1.6 GHz, and with high saturation power approaching -90 dBm at a gain of 22.8 dB. An i…
Visualization of the normal-fluid turbulence in counterflowing superfluid 4He
Alex Marakov, Jian Gao, Wei Guo +4
We describe a new technique, using thin lines of triplet-state He2 molecular tracers created by femtosecond-laser field-ionization of helium atoms, for visualizing the flow of the…
