The expansion of orthogonal complete set and transformation operator in teleportation
量子隐形传送态的正交完备基展开与算符变换

In accordance with the principle of superposition,for the teleportation of an arbitrary three-particle state via three pair nonmaximally entangled particles,the system state of particles can be expanded by Bell bases and transformation operator,and the teleportation can be realized only by performing a inverse transformation.The relation of transformation operators with unitary operation is discussed.The necessary condition to realize the teleportation is that the transformation operators have inverse operators.
