Quantum Jump Approach to Switching Process of a Josephson Junction Coupled to a Microscopic Two-Level System
Xueda Wen, Yiwen Wang, Ning Dong +6
With microwave irradiation, the switching current of a Josephson junction coupled to a microscopic two-level system jumps randomly between two discrete states. We modeled the switc…

Quantum Jumps between Macroscopic Quantum States of a Superconducting Qubit Coupled to a Microscopic Two-Level System
Yang Yu, Shi-Liang Zhu, Guozhu Sun +5
We report the observation of quantum jumps between macroscopic quantum states in a superconducting phase qubit coupled to the two-level systems in the Josephson tunnel junction, an…

Thermal Escape from a Metastable State in Periodically Driven Josephson Junctions
Guozhu Sun, Jian Chen, Weiwei Xu +7
Resonant activation and noise-enhanced stability were observed in an underdamped real physical system, i.e., Josephson tunnel junctions. With a weak sinusoidal driving force applie…
