摘要:

提出一个使用三能级原子以及通过经典场对单粒子态的操控和两原子与单模腔场的共振作用实现受控非门的方案。并使用该方案完成单粒子态的隐行传态过程。该方案中原子与单模腔场的共振作用时间可以很短,这一特点对量子信息处理过程中的消相干问题的处理是非常有利的,这也是该方案与已有文献报道的使用失谐腔的腔QED方案的主要区别之一。

Abstract:

A scheme to implement quantum Controlled-NOT(CNOT)gates with a resonant cavity is proposed and this quantum gate to carry out teleportation of an arbitrary single-atom superposition state is used. By using three level atoms our scheme can be realized through single-qubit operation and resonant interaction between two atoms and a resonant cavity. The interaction time between two atoms and the single-mode cavity is very short, which is important in view of decoherence. This character is one of the advantages of our scheme comparing to the scheme based on detuned cavity.

Key words: quantum information, quantum CNOT gate, teleportation, resonant cavity
