摘　　要：利用投影测量和正算子值测量,分别提出了以真五粒子非最大纠缠态为信道的双向受控隐形传态的两个协议。协议中,作为量子信道的真五粒子非最大纠缠态连接3个合法的参与者;在监督者Charlie的控制下,Alice以一定概率将任意未知单粒子A的态传给Bob,同时Bob也以一定概率将任意未知单粒子B的态传给Alice。这两个协议都是确定性双向隐形传态的推广。By using projective measurement and positive operator-valued measurement,two bidirectional controlled teleportation schemes via a genuine five-qubit non-maximally entangled state are proposed,respectively. In our scheme,such a five-qubit nonmaximally state is employed as the quantum channel linking three legitimate participants. And with certain probability,Alice many transmit an arbitrary unknown single-qubit state of qubit A to Bob and Bob many transmit an arbitrary single-qubit state of qubit B to Alice via the control of the supervisor Charlie. Our protocols are the generalization of deterministic bidirectional controlled teleportation.
