Charge-parity dynamics in offset-charge-sensitive transmons: Part 2*

Understanding and mitigating the effects of nonequilibrium quasiparticle excitations is an important step towards improving the performance of superconducting qubits. By designing transmon qubits in the offset-charge-sensitive regime, one can achieve direct dispersive detection of quasiparticle tunneling events. We utilize these devices to measure quasiparticle tunneling rates as a function of various experimental parameters such as RF filtering and qubit design. This talk will focus on experimental results.
