相位的物理意义及其在量子隐形传态中的重要性

The physical meaning of phase and its importance for quantum teleportation

S. J. van Enk

摘要:

我们认为,在量子隐形传态协议中,双方需要共享更多的资源,而不仅仅是一个纠缠态和一个经典的通信信道。由于正交状态之间的相位本身没有物理意义,因此需要定义所有相关相位的共享标准。我们讨论了量子比特的几种物理实现以及相应的相位的物理意义。

英文摘要:

We argue that the two parties in a quantum teleportation protocol need to share more resources than just an entangled state and a classical communication channel. As the phase between orthogonal states has no physical meaning by itself, a shared standard defining all relevant phases is necessary. We discuss several physical implementations of qubits and the corresponding physical meaning of phase.
