摘　　要：通过四能级原子与双模腔QED系统的谐振作用,提出实现三量子位Fredkin门功能的方案,其中原子量子态作为控制位,两个腔模量子态作为目标位.对方案的实验可行性进行讨论.A scheme is proposed for realization of three-qubit Fredkin gate for two intracavity modes with a four-level atom through the atom cavity resonant interaction in a cavity quantum electrodynamics system. In the presented protocol, the two states of the atom form the controlling qubit and the two quantized cavity-field modes act as the two target qubits. The experimental feasibility of our proposal are also discussed.
