【摘要】：光子源和纠缠光子对的制备是量子信息产生和传输过程的源头,是实现量子通信的重要前提条件。半导体量子点固体系统具有可集成性和可扩展性的优点,并且与现有的半导体光电子学技术密切相关,近年来在单光子源和纠缠光子对制备方面取得了重要的进展,是未来全固态量子通信的重要元器件。从量子通信的基本原理出发,阐述了制备单光子源和纠缠光子对的重要性,介绍如何解析推导出圆形常规半导体量子点中的电子结构,描述了圆形拓扑绝缘体量子点中边缘态具有双重简并的电子结构,能级间隔与量子点的具体形状无关,并且具有自旋轨道锁定的特性,总结了实验和理论上在利用这一独特的电子结构制备单光子源和纠缠光子对方面取得的重要进展。
[Abstract]:The preparation of photon source and entangled photon pair is the source of the generation and transmission of quantum information and an important prerequisite for quantum communication. Semiconductor quantum dot solid systems have the advantages of integration and scalability, and are closely related to the existing semiconductor optoelectronics technology. In recent years, important progress has been made in the preparation of single photon sources and entangled photon pairs. It is an important component of all solid state quantum communication in the future. Based on the basic principle of quantum communication, the importance of preparing single photon source and entangled photon pair is expounded, and how to analyze and deduce the electronic structure of circular conventional semiconductor quantum dots is introduced. This paper describes the double degenerate electronic structure of the edge state in the circular topological insulator quantum dot. The energy level interval is independent of the specific shape of the quantum dot and has the characteristics of spin orbit locking. The important progress in the preparation of single photon source and entangled photon surface by using this unique electronic structure is summarized.
