The advancement of quantum information hinges on the scalability of quantum systems to maintain non-local characteristics and improve the efficiency of quantum protocols. Strategies to enhance nonclassical correlations within quantum systems while mitigating decoherence phenomena are searing topics nowadays. Our study delves into the dynamics of nonclassical correlations within a two-qubit Heisenberg spin XXX model, utilizing Milburn’s dynamical master equation. We consider the impacts of anisotropic spin–orbit interactions, such as the Dzyaloshinskii–Moriya (DM) interaction and Kaplan–Shekhtman–Entin–Wohlman–Aharony (KSEWA) interaction, and employ three metrics, namely Bell’s inequality violation, concurrence, and local quantum uncertainty, to examine the dynamical features of nonclassical correlations under intrinsic decoherence. Our findings showcase the significance of the initial state of the two-qubit system in determining the parameters of spin–orbit interactions that influence the nonclassicality of the system. This underscores the critical role that DM and KSEWA interactions play in nonclassical correlations in solid-state quantum systems.

量子信息的进步取决于量子系统的可扩展性，以保持非局域特性并提高量子协议的效率。增强量子系统内的非经典相关性同时减轻退相干现象的策略是当今炙手可热的话题。我们的研究利用 Milburn 的动力学主方程，深入研究了两个量子位海森堡自旋 XXX 模型中非经典关联的动力学。我们考虑各向异性自旋轨道相互作用的影响，例如 Dzyaloshinskii-Moriya (DM) 相互作用和 Kaplan-Shekhtman-Entin-Wohlman-Aharony (KSEWA) 相互作用，并采用三个指标，即贝尔不等式违反、并发性和局部性。量子不确定性，以检查内在退相干下非经典相关性的动力学特征。我们的研究结果展示了两个量子位系统的初始状态在确定影响系统非经典性的自旋轨道相互作用参数方面的重要性。这强调了 DM 和 KSEWA 相互作用在固态量子系统的非经典关联中发挥的关键作用。
