由光分束器和起偏器混合产生的三模纠缠态表象

摘要

在三模Fock空间中,本文构建了一种新的三模连续变量纠缠态,它构成了一个新的量子力学表象.该态可以利用非对称光束分离器和起偏器实现.态的纠缠性通过获得其相应的施密特分解得以说明.作为该表象的一个重要应用,利用它实现了单粒子态的量子隐态传输,给出了相应的传输方案.%We constructed a new three-mode entangled state representation in the three-mode Fock space, which is complete and can make up a new quantum representation.This state can be generated experimentally by combining beamsplitter with polarizer.The entanglement properties are analyzed by obtaining its Schmidt decomposition.As an important application of this state, we consider a single-mode state teleportation by using this new state as a quantum channel, and present the corresponding teleportation scheme.
