摘要:
提出了三比特未知量子态的可控隐形传态方案,利用2个三方共享的4粒子团簇态作为量子信道,由第三方进行控制.首先,发送者(Alice)对其拥有的3个粒子对进行3次 Bell 基联合测量,并把结果通过经典信道告诉接收者(Bob)和控制者(Charlie).若控制者同意接收者重建未知量子态,则对自己的粒子对进行 Bell基测量,并将结果通知接收者.接收者根据发送者和控制者的测量结果,对自己拥有的粒子对做相应的幺正变换,就可以重建发送者要传的三比特未知的量子态,从而实现可控隐形传态
Abstract:
A scheme for controlled teleportation of an unknown three-qubit state using two four-qubit cluster states which are shared by a sender, a receiver and a controller as the quantum channel is proposed in detail. In the scheme, the sender(Alice) performs Bell-state measurement(BSM) on her qubits three times and then tells the receiver(Bob) and the controller(Charlie) her measured results via a classical channel.If the controller agrees the receiver to reconstruct the unkown quantum state, he performs the BSM on his qubits and tells the receiver his measured result. According to the results from both the sender and the controller, the receiver could reconstruct the unkown three-qubit state by performing some appropriately unitary transformations on his qubits. Thus the controlled teleportation of an unknown three-qubit state is achieved.
