我们测量了，在真实的时间，单个准粒子隧穿在一个单一的库珀对晶体管，使用超电流分支的射频反射计。我们通过分析晶体管的偶态和奇态的停留时间分布，直接提取了偶-奇和奇-偶跃迁速率。我们讨论了测量和分析技术，并报告准粒子隧穿率的温度和门依赖性。
We have measured, in real time, individual quasiparticle tunneling in a single-Cooper-pair transistor, using rf reflectometry on the supercurrent branch. We have extracted the even-to-odd and odd-to-even transition rates directly by analyzing the distributions of dwell times in the even and odd states of the transistor. We discuss both the measurement and analysis techniques and report on the temperature and gate dependence of the quasiparticle tunneling rates.
