Distinguishing parity-switching mechanisms in a superconducting qubit

Spencer Diamond, Valla Fatemi, Max Hays +8

Single-charge tunneling is a decoherence mechanism affecting superconducting qubits, yet the origin of excess quasiparticle excitations (QPs) responsible for this tunneling in supe…

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…

Hot non-equilibrium quasiparticles in transmon qubits

K. Serniak, M. Hays, G. de Lange +6

Non-equilibrium quasiparticle excitations degrade the performance of a variety of superconducting circuits. Understanding the energy distribution of these quasiparticles will yield…

Direct microwave measurement of Andreev-bound-state dynamics in a proximitized semiconducting nanowire

M. Hays, G. de Lange, K. Serniak +6

The modern understanding of the Josephson effect in mesosopic devices derives from the physics of Andreev bound states, fermionic modes that are localized in a superconducting weak…
