Teleportation of a two-qubit unknown atomic state through the Raman interaction of A-type three-level atom witha coherent state cavity-field

实现量子态的隐形传送,尤其是多比特量子态的隐形传送在量子信息领域中有非常重要的作用。提出了一种隐形传送两比特未知原子态方案。在此方案中,用一个三粒子纠缠态作为量子信道,传送两比特未知原子态。

Realizing the teleportation of a quantum state, specially the teleportation of a many-qubit quantum state, is of great importance in quantum information. A scheme of teleporting a two-qubit unknown atomic state was proposed. In this scheme, a three-particle entangled state is used as quantum channel to teleport a two-qubit atomic state.
