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…

Mach-Zehnder Interferometry in a Strongly Driven Superconducting Qubit
William D. Oliver, Yang Yu, Janice C. Lee +3
We demonstrate Mach-Zehnder-type interferometry in a superconducting flux qubit. The qubit is a tunable artificial atom, whose ground and excited states exhibit an avoided crossing…

Energy Relaxation Time between Macroscopic Quantum Levels in a Superconducting Persistent Current Qubit
Yang Yu, D. Nakada, Janice C. Lee +5
We measured the intrawell energy relaxation time τ_{d} between macroscopic quantum levels in the double well potential of a Nb persistent-current qubit. Interwell population transi…
