论文摘要
我们研究了两个腔和两个储层系统的局部量子不确定性（LQU）的动力学。一开始，被视为两个量子位的腔相互关联，而储层既不相互关联，也不与腔相关。我们回答了这项工作的两个主要问题。首先，局部量子不确定性如何从两个量子相关的腔体中衰减并在储层之间生长。第二个问题是对四个量子位之间的LQU进行的检查，还阐明了其动力学。我们观察到，LQU在储层之间形成了一种镜像形象，从而从空腔中腐烂。对于四个量子位，我们建议如何计算LQU，以使该方法具有直观的且符合观察结果。我们发现，在四个量子位中，LQU在零值开始生长到最大值，然后再次衰减到零，因为渐近状腔状态完全转移到储层中。我们建议实现我们的结果的实验设置。
We study dynamics of local quantum uncertainty (LQU) for a system of two cavities and two reservoirs. In the start, the cavities treated as two qubits are quantum correlated with each other, whereas reservoirs are neither correlated with each other nor with cavities. We answer two main questions in this work. First, how local quantum uncertainty decays from two quantum correlated cavities and grows among reservoirs. The second question is the examination of LQU developed among four qubits and also shed some light on its dynamics. We observe that LQU develops among reservoirs as kind of mirror image to its decay from cavities. For four qubits, we propose how to compute LQU such that the method is intuitive and conformable to the observation. We find that among four qubits LQU starts growing from zero to maximum value and then decays again to zero as the asymptotic state of cavities is completely transferred to reservoirs. We suggest the experimental setup to implement our results.
