摘　　要：利用耦合多原子同时与单模腔场的非共振相互作用,提出了一个1→2的通用量子克隆机方案。该方案装置简单,仅需三个单模腔场和一个经典场,且在制备过程中腔场可始终处于真空态。也分析了该方案在实验上的可行性。A scheme for implementing a universal 1→2 quantum cloning machine is proposed. The process of the cloner is achieved through the nonresonant Jaynes-Cummings model of atoms simultaneously interacting with single-mode cavity field in the vacuum state. The proposed scheme only requires three single-mode cavity fields and one classical field, thus it is easier to be realized in experiment by using cavity QED technique. The experimental feasibility of the proposed scheme is also discussed.
