用于纠缠态隐形传态的多体纠缠

Multipartite entanglement for entanglement teleportation

Jinhyoung Lee, Hyegeun Min, Sung Dahm Oh

摘要:

提出了一种利用四个量子比特的多体纠缠作为量子信道的纠缠隐形传态方案。基于纠缠隐形传态在任意两比特幺正变换下的不变性,推导了发送端联合测量和接收端幺正操作的分离度关系.从可分离性的关系可以看出,不可分离的量子信道总是导致纠缠态的完全隐形传态,而不可分离的联合测量和/或非局域幺正操作是不可分离的.

英文摘要:

The scheme for entanglement teleportation is proposed to incorporate multipartite entanglement of four qubits as a quantum channel. Based on the invariance of entanglement teleportation under arbitrary two-qubit unitary transformation, we derive relations of separabilities for joint measurements at a sending station and for unitary operations at a receiving station. From the relations of separabilities it is found that an inseparable quantum channel always leads to a total teleportation of entanglement with an inseparable joint measurement and/or a nonlocal unitary operation.
