Abstract
In this paper, a scheme is proposed for performing remote operationon quantum state among multiparty. We use three-particle GHZ state as quantumchannels to prepare a state operator, which describes quantum correlationbetween states and operations. Based on the special characteristic of thestate operator, observers can perform unitary operation on a system that isaway from observers. Our studies show this process is deterministic. Wefurther consider remote operation among N spatially distributed observers,and the results show the successful realization of remote operation needscollective participation of N parties, that is, there exists strongcorrelation among multiparty. In addition, we investigate the case in whichobservers share a three-particle W state as quantum channels to performremote operation and studies find this process is probabilistic.
