四粒子任意纠缠态的控制隐形传输
The Theoretical Analysis of Controlled Teleportation of Four-particle Arbitrary Entangled State
【摘要】 隐形传送体系的总量子态的实质是完备基展开与变换算符的线性叠加,若变换算符可逆,且为幺正算符,则进行相应的逆幺正变换操作即可实现量子态的隐形传送;若变换算符不可逆,则不能实现任意量子态的隐形传送。本文由变换算符给出四粒子任意纠缠态的控制隐形传输的理论分析,给出控制方对拥有的粒子进行Hadamard门变换与不进行Hadamard门变换的解释。
【Abstract】 A theoretical analysis is proposed for the controlled teleportation of four-particle arbitrary entangle state.The systematic state of particles can be expanded by Bell bases and transformation operators.If transformation operators have inverse operator,the teleportation can be realized only by performing some transformations.If the transformation operators have no inverse operator,then teleportation can not be realized.
