摘要: 提出了隐形传送体系的总量子态实质是Bell基矢与变换算符的线性叠加,若变换算符可逆,则进行相应的逆变换操作即可实现量子态的隐形传送;若变换算符不可逆,则不能实现量子态的隐形传送;并且发现,变换算符的行列式与粒子的纠缠度有直接关系.

Abstract: In teleportation,the system state is linear combination of Bell bases and transformation. If transformation operators have inverses operators, the teleportation can be realized by performing a inverse transformation. The relation of the determinant of transformation operators with entanglement measure is obtained.

Key words: teleportation, transformations operator, entangled state
