摘要
We measured experimentally the spectrum of a superconducting phase qubit.An avoided energy-level crossing is obviously observed,which is due to the coupling to a microscopic two-level system.With different theoretical methods,we simulated the spectrum,from which we can obtain the coupled system’s parameters and the coupling mechanism.
