摘要
提出了一个利用束缚在高Q腔中的超导量子干涉仪(SQUID)来实现近似给定态克隆机的方案.在实现克隆机的过程中,控制非(CNOT)操作必不可少,其操作可以通过调节SQUID与微波腔的相互作用来得到.由于目前在实验上SQUID技术很容易被完成,本方案在实验上也是可行的.
We present a scheme to implement a quantum cloning machine which copies a state near a given one with superconducting quantum-interference device（SQUID） embedded in a high-Q cavity. The controlled-NOT operations derived in our scheme are indispensable for the preparation of this cloning machine, which can be implemented by adjusting the interaction between the SQUID and the microwave cavity. Due to the technology of SQUID can be easily implemented in current experiment, our scheme also can be realized in experiment.
