摘要: Implementation of a nonlocal multi-qubit conditional phase gate is an essential requirement in some quantum information processing (QIP) tasks. Recently, novel solid-state cavity electrodynamics (QED) system, which the nitrogen–vacancy (NV) center diamond coupled to microtoroidal resonator (MTR), has been proposed as potential system for hybrid and computing. By virtue such systems, we present scheme realize N-qubit directly. Our employs input–output process single-photon interference, without use any auxiliary entanglement pair or classical communication. Considering currently available technologies, our might be quite useful among different nodes networks large-scaled QIP.
