Non-Local and Non-Markovian Effects of a Microscopic Two-Level Defect in Superconducting Quantum Circuits
Yang Gao, Yujia Zhang, Huikai Xu +12
Microscopic two-level systems (TLS) -- ubiquitous atomic-scale defects in solid-state quantum devices -- are a dominant source of qubit decoherence, yet their role is often conside…
Characterizing charge-parity detection based on an offset-charge-tunable transmon qubit via randomized benchmarking
Yao-Yao Jiang, Tang Su, Yuxiang Liu +11
Superconducting qubits are compelling platforms for charge-parity detection and, due to their theoretical sensitivity on the meV energy scale, hold promise for rare event searches.…
Dressed-state relaxation in coupled qubits as a source of two-qubit gate errors
