Coherent manipulation of an Andreev spin qubit
M. Hays, V. Fatemi, D. Bouman +9
Two promising architectures for solid-state quantum information processing are electron spins in semiconductor quantum dots and the collective electromagnetic modes of superconduct…
Spin Coherent Manipulation in Josephson Weak Links
Javier Cerrillo, Max Hays, Valla Fatemi +1
Novel designs of Josephson weak links based on semiconducting nanowires combined with circuit QED techniques have enabled the resolution of their fine structure due to spin-orbit i…
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…
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…
