摘要

本研究探讨了非对称耦合双量子点的量子信息动力学，分析了对称、初始态和库仑相互作用对相关保持的影响。结果表明，对称性增强了纠缠的鲁棒性，而非对称性和高纠缠增加了退相干的灵敏度。强库仑相互作用支持保真度和容量保持。这些见解与优化协议相关，例如在退相干环境中密集编码和隐形传态。

Asymmetric Rate and Its Impact on Communication Protocol Dynamics in Coupled Double Quantum Dot Systems

This study explores quantum information dynamics in asymmetrically coupled double quantum dots, analyzing the effects of symmetry, initial state, and Coulomb interactions on correlation preservation. Results show that symmetry enhances entanglement robustness, while asymmetry and high entanglement increase sensitivity to decoherence. Strong Coulomb interactions support fidelity and capacity retention. These insights are relevant for optimizing protocols such as dense coding and teleportation in decohering environments.
