关于连续变量的隐形传态

On the Teleportation of Continuous Variable

S. N. Molotkov, S. S. Nazin

摘要:

从量子力学测量的一般理论出发,分析了量子隐形传态的测量过程。它表明,要找到隐形传态应该只知道的身份决议(积极的运营商价值的措施)所产生的相应的仪器(量子操作描述的系统状态变化所造成的测量),而不是仪器本身。针对非简并连续谱系统,提出了一种基于非正交单位分辨测量的量子隐形传态方案。

英文摘要:

The measurement procedures used in quantum teleportation are analyzed from the viewpoint of the general theory of quantum-mechanical measurements. It is shown that to find the teleported state one should only know the identity resolution (positive operator-valued measure) generated by the corresponding instrument (quantum operation describing the system state change caused by the measurement) rather than the instrument itself. A quantum teleportation protocol based on a measurement associated with a non-orthogonal identity resolution is proposed for a system with non-degenerate continuous spectrum.
