轨道角动量量子光源的集成化研究
Research progress of integrated quantum light sources with orbital angular momentum
摘要
Abstract
Quantum light sources are one of key devices for quantum information processing,and they are also the important foundation for applications such as in quantum computing,quantum communication,and quantum simulation.Improving the capacity of quantum information coding by using the quantum light source is a major challenge in the development of quantum information technology.Photons with a helical phase front can carry a discrete,unlimited but quantized amount of orbital angular momentum(OAM).The infinite number of states with different OAMs can greatly increase the capacity of optical communication and information processing in quantum regimes.To date photons carrying OAM have mainly been generated by using bulk crystals,which limits the efficiency and the scalability of the source.With the advancement of quantum photonic technology,many significant quantum photonic devices can now be realized on integrated chips.However,creating high-dimensional OAM quantum states at a micro-nano scale is still a challenge.And the research of harnessing high-dimensional OAM mode by using integrated quantum photonic technologies is still in its infancy.Here,the authors review the recent progress and discuss the integrated quantum light sources with OAM.The authors introduce the research progress of using OAM for both single photons and entangled photons and emphasize the exciting work on pushing boundaries in high-dimensional quantum states.This may pave the way for the research and practical applications of high-dimensional quantum light sources.关键词
