  • 提出了一种量子信息转移方案,它是基于两个耦合的二能级原子同时与单模腔场发生大失谐相互作用实现的.通过控制腔场与双原子的相互作用时间,量子信息可以从一个原子转移到另一个原子,或从单模腔场转移到双原子纠缠态上,而包含在欲转移量子态上的信息被完全檫除.

     

    We present a scheme for transferring quantum information, which is based on the nonresonant interaction of two two_level atoms with a single_mode cavity field. We show that quantum information can be transferred from one atom to another atom, and from cavity mode to two atoms by manipulating the interactions between cavity field and two atoms, and the information contained in the transferred atom or cavity mode is completely erased.
