摘　　要：提出一种利用耦合双原子与单模光场相互作用系统实现控制非门的方案.结果表明:腔场初始时刻制备于相干态,双原子处于特定的初态.在大失谐相互作用情况下,通过控制腔场与耦合双原子的相互作用时间,就可以实现控制非门.A scheme is proposed by which controlled-NOT gate is implemented using the system of interaction between the coupling double atoms and the single-mode optical field. The cavity field is prepared initially in the coherent state while the double atoms are in a specific primary state. Under the condition of large detuning, controlled-NOT gate can be achieved by controlling the time of interaction between the cavity field and the double atoms.
