Quantum State Transfer for Two Atoms with a Single Resonant Interaction

摘要

＜正＞ We present a scheme for transferring an unknown atomic entangled state with a single resonant interaction.This scheme only requires a single resonant interaction of two atoms with a cavity mode and does not use the cavitymode as the memory.Thus the scheme is very simple and the interaction time is very short,which is important inview of decoherence.Quantum state can be directly transferred from two atoms to another two atoms with a successfulprobability of 100 percent.
