具有非理想条件局部操作的隐形传送协议

Teleportation protocol with non-ideal conditional local operations

C. Di Franco, D. Ballester

摘要:

在量子隐形传态的标准协议中,假设鲍勃能够对他的量子比特进行理想的操作。在这里,我们分析的情况下,其中一些操作比其他操作更可靠。此外,我们认为Alice和Bob共享的信道是非最大纠缠的。在这种情况下,可以通过适当选择Alice进行双量子比特测量的基来最大化隐形传态的平均保真度。

英文摘要:

In the standard protocol for quantum teleportation, one assumes that Bob is able to perform ideal operations on his qubit. Here, we analyze the case in which some of these operations are more reliable than others. Moreover, we consider the channel shared by Alice and Bob as non-maximally entangled. In this context, the average fidelity of teleportation can be maximized by properly choosing the basis in which Alice performs her two-qubit measurement.
