利用腔QED实现量子态转移

Transfer of an unknown quantum state via cavity QED

利用两个二能级原子和用光纤联接的两个单模光腔构成的系统,给出了实现量子态转移的方案.该方案中两个二能级原子分别处于用光纤联接的单模腔中,并同时与光场发生共振相互作用.通过控制原子与光场的相互作用时间,实现量子态的转移.

A scheme for the distant transfer of a quantum state is presented. In the scheme, two two-level atoms interact with single-mode cavities which are connected by an optical fiber separately. The results show that the atomic quantum state, the quantum state of cavity field or the entanglement state between atom and cavity field can be transferred by manipulating the interactions between cavities and two atoms.
