In this paper, we address the dynamics of nonclassical correlation, quantified by local quantum uncertainty (LQU) in a two-qubit system subjected to classical environmental noise when the initial states of system are prepared in a specific class of Bell states. Two different configurations of the local noisy environment are examined. In the first case, we consider a system of two independently qubits, each locally interacting with its classical random noise, whereas in the second case we consider only one of qubits subject to a classical random noise. Our results show that the dynamics of LQU is strongly related to both the dephasing and relaxation factors. The behaviors of LQU in above two cases exhibit similar variation, with monotonic decay in the weak coupling region, while revivals in the strong coupling region depending on the ratio of the switching rate and coupling strength to the qubit. By controlling this ratio, long-time survival of LQU is obtained. Therefore, our res...

经典环境噪声导致的两量子位系统中的局部量子不确定性

在本文中，当系统的初始状态准备成特定的贝尔状态类时，我们讨论了非经典相关性的动力学，该动力学通过局部量子不确定性（LQU）在经受经典环境噪声的两量子位系统中进行量化。研究了本地嘈杂环境的两种不同配置。在第一种情况下，我们考虑一个由两个独立的量子比特组成的系统，每个量子比特都与它的经典随机噪声局部相互作用，而在第二种情况下，我们只考虑其中一个量子比特受到经典随机噪声的影响。我们的结果表明，LQU的动力学与移相和松弛因子都密切相关。在以上两种情况下，LQU的行为表现出相似的变化，在弱耦合区域具有单调衰减，而强耦合区的恢复取决于开关速率和量子位的耦合强度。通过控制该比例，可以获得LQU的长期存活率。因此，我们的资源...
