论文摘要
通过直接监测读出谐振器的色散转移来测量全壳超导体 - 纳米旋转量子量子量子中的电荷 - 差转换速率。在零磁场上，测得的切换时间尺度$ t_p $在100毫秒内。在电荷范围上选择的两色调光谱数据已被证明。随着温度或磁场的升高，TP首先是恒定的，然后被指数抑制，与包括非平衡和热活化的准粒子的模型一致。随着TP的抑制，量子寿命T1也会减少。零字段的长$ t_p \ sim 0.1 $ s有望根据混合纳米线的将来开发Qubits。
The rate of charge-parity switching in a full-shell superconductor-semiconductor nanowire qubit is measured by directly monitoring the dispersive shift of a readout resonator. At zero magnetic field, the measured switching time scale $T_P$ is on the order of 100 ms. Two-tone spectroscopy data post-selected on charge-parity is demonstrated. With increasing temperature or magnetic field, TP is at first constant, then exponentially suppressed, consistent with a model that includes both non-equilibrium and thermally activated quasiparticles. As TP is suppressed, qubit lifetime T1 also decreases. The long $T_P\sim 0.1$ s at zero field is promising for future development of qubits based on hybrid nanowires.
