中文摘要：

提出一种1→2相位协变量子克隆的腔QED实现方案，该克隆过程是基于原子与两个高Q腔场的相互作用来实现的。腔场最初处于真空态。虽然该方案需要实现CNOT操作，但与其它方案相比该方案需要的操作更加简单方便，并且该方案里所使用的基本操作（受控量子门操作和经典场脉冲操作）都已经得到充分的验证。所以我们相信该方案能在实验上实现。

英文摘要：

A scheme is proposed to realize 1→2 phase-covariant quantum cloning machine in cavity electrodynamics. This clone machine acts on the electronic states of atoms that interact with electromagnetic fields of two high-Q cavities. The cavity fields are initially prepared in the vacuum states. Although CNOT operations are needed, fewer operations are required than other schemes and the basic operations （controlled quantum gates and classical field pulses） are thoughtfully tested.
