Abstract

We develop a theoretical scheme for creating coupling between nitrogen-vacancy (N-V) ensemble and superconducting qubit using a transmission line resonator. Through adjusting local external flux threading the superconducting qubit loop, the desired coupling between random superconducting qubit and transmission line resonator is obtained at will. Moreover, the flexible two-qubit controlled phase gate is realized. Also, our protocol might be implemented via the current experimental technology.
