论文摘要
我们探讨了非马克维亚通道对具有不同等级的均匀生成的随机两数分输入状态的量子相关性（QC）的影响 - 通过嘈杂的通道传递了具有不同等级的级数（单面）或两个量子位（双面）或两个Qubits（双面）。在以不同的非马克维亚强度，输出状态的纠缠和量子不一致的不同之后，输出状态崩溃并随着噪声的增加而恢复，在变化和去极化通道下。我们发现，在去极化双面通道的情况下，随机状态的两个QC平均复兴数量比具有固定的非马克维亚强度的单侧QC平均比单面的复兴数量更高，而与国家等级无关 - 我们称这种反直觉的事件是非宣传性的建设性反馈。因此，随机状态的QC的平均噪声随着非马克维亚噪声的强度的增加而降低了首次复兴，从而表明即使存在高噪声，非马克维亚通道在QC的再生中的作用。但是，我们观察到，非马克维亚性并不发挥任何作用来增加随机量子状态的鲁棒性，这可以通过量子相关性首次崩溃的临界噪声的平均值来衡量。此外，我们观察到，随着随机输入状态的平均QC的增加以及非马克维亚性，一个国家显示出再生的趋势会增加。
We explore the impact of non-Markovian channels on the quantum correlations (QCs) of Haar uniformly generated random two-qubit input states with different ranks -- either one of the qubits (single-sided) or both the qubits independently (double-sided) are passed through noisy channels. Under dephasing and depolarizing channels with varying non-Markovian strength, entanglement and quantum discord of the output states collapse and revive with the increase of noise. We find that in case of the depolarizing double-sided channel, both the QCs of random states show a higher number of revivals on average than that of the single-sided ones with a fixed non-Markovianity strength, irrespective of the rank of the states -- we call such a counter-intuitive event as a constructive feedback of non-Markovianity. Consequently, the average noise at which QCs of random states show first revival decreases with the increase of the strength of non-Markovian noise, thereby indicating the role of non-Markovian channels on the regenerations of QCs even in presence of a high amount of noise. However, we observe that non-Markovianity does not play any role to increase the robustness in random quantum states which can be measured by the mean value of critical noise at which quantum correlations first collapse. Moreover, we observe that the tendency of a state to show regeneration increases with the increase of average QCs of the random input states along with non-Markovianity.
