摘要
Abstract
A scheme is proposed to implement a quantum controlled-phase gate between two four-level atoms inside the different optical cavities.The scheme combines the advantage of scalability from the photon and power of strong atom-photon coupling,which yields the desired unitary evolution operation.The scheme is immune to decoherence due to cavity photon decay and atomic spontaneous emission,and the operation is implemented probabilistically with a very high fidelity.关键词
