论文摘要

在这一贡献中,我们使用了受记忆,去驱动和振幅阻尼通道的抗熔通道影响的钟状态,研究了单量状状态的双向量子遗传(BQT)。还评估了负量子量子通道中剩余的纠缠,传送保真度和量子渔民信息的纠缠的量度。我们发现,这两个最后量都取决于BQT量子通道中的纠缠的存活量,在变质通道的变质因子和相关程度上。我们表明,在马尔可夫政权中,通过考虑经典的渠道相关性,负面的,传送平均保真度和量子渔民信息略有增强。此外,在非马克维亚政权中,可以长时间改善这三个数量。

In this contribution, we have investigated the bidirectional quantum teleportation (BQT) of single-qubit states using a Bell state influenced by decoherence channels with memory, dephasing and amplitude damping channels. The expressions of the negativity, as a measure of the entanglement remaining in the BQT quantum channel, the teleportation fidelities and the quantum Fisher information are also evaluated. We find that both these last quantities depend on the survival amount of entanglement in the BQT quantum channel, on the decoherence factor and on the correlation degree of the decoherence channel. We show that in the Markovian regime, the Negativity, the teleportation average fidelities and the quantum Fisher information are slightly enhanced by considering the classical channel correlations. Besides, in the non-Markovian regime, these three quantities could be improved for a long period of time.
