论文摘要
我们报告了从铝纳米布里奇（Nanobridge）的铝制固定状态捕获和清除的准颗粒诱捕和清除的连续测量，该铝纳米架约瑟夫森交界处集成到超导量Qubit-Qubit样装置中。我们发现，诱捕是通过独立自发发射事件进行很好建模的。在80 MK以上，通过吸收热声子的吸收可以很好地描述清除过程，但其他与温度无关的机制在低温下占主导地位。我们发现低温清除速率对安里森结合状态能的依赖性中的复杂结构。我们的结果阐明了Qubit样电路中的准粒子行为。
We report continuous measurements of quasiparticles trapping and clearing from Andreev Bound States in aluminum nanobridge Josephson junctions integrated into a superconducting-qubit-like device. We find that trapping is well modeled by independent spontaneous emission events. Above 80 mK the clearing process is well described by absorption of thermal phonons, but other temperature-independent mechanisms dominate at low temperature. We find complex structure in the dependence of the low-temperature clearing rate on the Andreev Bound State energy. Our results shed light on quasiparticle behavior in qubit-like circuits.
