Waiting time distributions in a two-level fluctuator coupled to a superconducting charge detector

Máté Jenei, Elina Potanina, Ruichen Zhao +7

We analyze charge fluctuations in a parasitic state strongly coupled to a superconducting Josephson-junction-based charge detector. The charge dynamics of the state resembles that…
