Direct Dispersive Monitoring of Charge Parity in Offset-Charge-Sensitive Transmons
Direct Dispersive Monitoring of Charge Parity in Offset-Charge-Sensitive Transmons
Improving the coherence of superconducting qubits is a crucial step toward the goal of fault-tolerant quantum processors based on them. An ongoing experimental challenge is to diagnose and mitigate the dominant decoherence mechanisms. In this work, the authors demonstrate a method of probing the decoherence induced by nonequilibrium superconducting quasiparticles, …
