| 摘 要： | 采用4个EPR(Einstein-Podolsky-Rosen)对作为量子信道,提出一种新的全概率联合远程制备任意四粒子Cluster类态方案。在这个新的方案中,一个制备者执行四粒子投影测量,另一个制备者对手中的粒子执行二粒子投影测量。然后,接收者对手中二粒子进行某种幺正操作,并分别对两个辅助粒子进行受控非门操作,从而最终得到需要制备的Cluster类态。与其他制备任意四粒子Cluster类态的全概率制备方案相比,所提协议效率较高,而且在实验上更经济可行。

| Abstract: | Taking four EPR (Einstein-Podolsky-Rosen) pairs as quantum channel,a new protocol for deterministic joint remote preparation of four-particle cluster-type states was presented.In the protocol,one of the senders performs a four-qubit projective measurement,while the other performs a bipartite projective measurement.Afterwards,the receiver just adopts some appropriate unitary operations on his/her own two particles,and then respectively applies a controlled-NOT gate on two other auxiliary particles.As a result,he/she can obtain the desired state.Compared with other protocols for deterministic remote preparation of arbitrary four-particle cluster-type states,our protocol is more efficient,and it is economic and feasible in the physical experiment. |
