Continuous monitoring of a trapped, superconducting spin
M. Hays, V. Fatemi, K. Serniak +7
Readout and control of fermionic spins in solid-state systems are key primitives of quantum information processing and microscopic magnetic sensing. The highly localized nature of…

Photon-assisted charge-parity jumps in a superconducting qubit
M. Houzet, K. Serniak, G. Catelani +2
We evaluate the rates of energy and phase relaxation of a superconducting qubit caused by stray photons with energy exceeding the threshold for breaking a Cooper pair. All channels…

Direct Dispersive Monitoring of Charge Parity in Offset-Charge-Sensitive Transmons
K. Serniak, S. Diamond, M. Hays +5
A striking characteristic of superconducting circuits is that their eigenspectra and intermode coupling strengths are well predicted by simple Hamiltonians representing combination…
