摘要
利用非线性元件交错相位反转器和激光分束器制备三模纠缠相干态作为量子隐形传态的信道,同时通过引入辅助模和采用阈探测器对光子数的探测,实现两模纠缠相干态的量子隐形传送.
A scheme for faithful teleportation of an unknown optical two-mode entangled coherent states is proposed.The three-mode entangled coherent states which is used as the quantum channel in this scheme can be prepared with the nonlinear optical elements.The scheme can be realized using ancillary modes and the threshold detectors for measurement.
