提出一种利用腔QED技术,实现无Bell基测量的经济相位传输克隆方案.该方案主要是基于原子和腔共振模型,其主要优点为:(1)由于利用了原子的共振,使整个过程所需时间大大缩短;(2)不需要任何的单比特原子旋转操作,实验装备较简单.在当前的实验技术条件下,该方案是可以实现的.
A scheme for telecloning without the Bell-state measurement on cavity QED is proposed. The present protocol is based on the resonance of the atoms and the cavity mode. The advantages of the proposal are mainly as follows. One is that the required time for the whole procedure is short due to the resonance. The other one is that we need no any single-qubit rotating operation on the atoms, which makes the experimental setup simple. Furthermore, the present scheme is feasible based on currently available technologies.
