基于半导体量子点的量子通信
Quantum communication based on semiconductor quantum dots
摘要
Abstract
The preparation of single photon sources and entangled photon pairs is the key to generation and transmission of quantum information,which is also an important prerequisite for quantum communication.Semiconductor quantum dot with high integration and expansion,closely related with the recently semiconductor optoelectronics technology,has made great progress in recent years for the preparation of single photon sources and entangled photon pairs,which must be an important component of solid state quantum communication in the future.In this review,we introduce the basic principles of quantum communication and explain the significance of design and implementation of single photon sources and entangled photon pairs with quantum dot.The electronic structures of conventional semiconductor quantum dots and topological insulator quantum dots are discussed,especially the electronic structure of the edge states in a circular topological insulator quantum dot has a double degeneracy,the electronic structures are independent of the shape of the quantum dot,and show spin-angular momentum locking.Finally,we present how to take advantage of the electronic structure of quantum dot for the preparation of single photon sources and entangled photon pairs,and great progress has been achieved in this field.关键词
