利用拉曼型的Jaynes-Cummings模型传送两比特的未知原子态

Teleportation of a Two-Qubit Atomic State Through the Raman Atom-Cavity-Field Interaction

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的方案。在此方案中 ,用两个两粒子纠缠态代替一个三粒子纠缠态作为量子信道 ,而且此方案可推广到隐形传送N比特的未知原子态。

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 is proposed. In this scheme, two pairs of entangled states are used as quantum channel instead of using a three-particle entangled state. And this scheme can also be generalized for the teleportation of the N-qubit atomic state.
