正则量子隐形传态

Canonical Quantum Teleportation

Sixia Yu, Chang-Pu Sun

摘要:

正则共轭观测量如位置-动量和相位-数在量子隐形传态中扮演着三重角色。首先,两个可交换的正则观测量(如相位差和数和)的公共本征态提供了两个系统之间的量子信道。其次,在Bell算符测量中测量了另外两个系统的一对相似的正则可观量。

英文摘要:

Canonically conjugated observables such as position-momentum and phase-number are found to play a 3-fold role in the drama of the quantum teleportation. Firstly, the common eigenstate of two commuting canonical observables like phase-difference and number-sum provides the quantum channel between two systems. Secondly, a similar pair of canonical observables from another two systems is measured in the Bell operator measurements.
