论文摘要
EPR转向是量子信息和计算中重要的量子资源。在本文中，研究了其在量子传送中的应用。首先，得出了基于EPR转向的平均传送保真度的上限。当接收器只能执行身份或保利旋转操作时，违反三设定线性转向不等式的X型状态可用于传送。最后，转向观测值和双Quibent降低状态的平均传送效率，用于三度纯状态，保持相同的顺序。还建立了可观察到的可观察到的互补关系与三量纯状态的平均传送保真度之间的互补关系。
EPR steering is an important quantum resource in quantum information and computation. In this paper, its applications in quantum teleportation are investigated. First of all, the upper bound of the average teleportation fidelity based on the EPR steering is derived. When the receiver can only perform the identity or the Pauli rotation operations, the X-type states which violate the three-setting linear steering inequality could be used for teleportation. In the end, the steering observables and the average teleportation fidelities of the two-qubit reduced states for three-qubit pure states maintain the same ordering. The complementary relations between the steerable observables and the average teleportation fidelities for three-qubit pure states are also established.
