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.…

Novel Light Dark Matter Detection with Quantum Parity Detector Using Qubit Arrays
Xuegang Li, Yuxiang Liu, Jing Shu +6
We present the design and the sensitivity reach of the Qubit-based Light Dark Matter detection experiment. We propose the novel two-chip design to reduce signal dissipation, with q…
