利用连续变量量子克隆机实现隐形传态

Teleportation using continuous variable quantum cloning machine

Satyabrata Adhikari

摘要:

利用连续变量量子克隆机(变换)产生的三模纠缠,可以实现相空间中未知量子态的隐形传态。此外,继续我们的隐形传态协议,我们能够提高保真度的隐形传态获得的Look等人。84,3482(2000)]。本文还研究了克隆机输出的两个拷贝之间的纠缠。

英文摘要:

We show that an unknown quantum state in phase space can be teleported via three-mode entanglement generated by continuous variable quantum cloning machine (transformation). Further, proceeding with our teleportation protocol we are able to improve the fidelity of teleportation obtained by Loock et.al. [Phys.Rev.Lett. 84, 3482(2000)]. Also we study here the entanglement between the two output copies from cloning machine.
