中文摘要： 量子纠缠网络应用了量子纠缠所独有的特性，可突破现有经典网络的物理极限，具有更强信息存贮、处理和传输能力。自组装量子点容易集成和扩展，并且具有很强的光控性，所以是很好的储存比特。而自组装量子点分子具有更加丰富的能级结构，近年来也成为研究热点。随着量子点和腔技术的进步，实验上已经实现了腔和自组装量子点的强耦合。基于此我们将开展腔和自组装量子点分子组成的复合系统量子纠缠网络的研究。其主要内容是：研究腔-自组装量子点分子系统中纠缠动力学演化的相关理论问题及其在量子网络中的应用；探索腔中自组装量子点分子中电子各个能级之间的量子操控；构建通过相干光（或压缩光）干涉来实现腔-自组装量子点分子系统的量子纠缠网络的方案。

英文摘要： The quantum entanglement network have many advantage over the classical network, such as large storage, fast information processing and transmission. The self-assembled quantum dots can be as ideal storage qubits because can be well fabricated and fast controlled by lasers. Much attention has been drawn to the self-assembled quantum dot molecules because that have richer energy structures than single quantum dots and could easily controlled by lasers. Recently, some researchers show that the self-assembled quantum dots can be strongly coupled to photonic cavities, this kind of system can be used as the interface between the flying and storage qubits. For these reasons, we propose this project to study the quantum dot molecule-cavity system, and built the quantum entanglement network with them. The main contents of this project are the follows: research on the dynamic of the system and their application in quantum entanglement network; explore the control of energy level of single self-assembled quantum dot molecule; built the quantum entanglement network with this system via coherent (or squeeze) light interference.
