摘　　要：高次谐波产生过程是一种广泛、成熟、可行的制备相干量子光源的方案,在新兴的X射线量子光学领域有望得到应用。目前,量子光学已经在微波和可见光波段研发了诸如压缩态制备、诱导透明、高次谐波产生、多波混频等应用。X射线因其高精度、高衍射极限、鲁棒性、穿透性和聚焦能力在理论上优于目前广泛采用的微波和可见光波段,在X射线波段下研发量子光学模型、量子信息单元和量子光学元件,有助于推动其向精密化,小型化发展。最近的研究将量子光学推广至X射线波段,产生了诸如X能标下的量子系统、单光子、脉冲、高次谐波产生相干X射线脉冲等创新性研究成果,发展了阿秒级的相干X射线量子光源。X射线光学与量子光学的交叉正在引来越来越多的关注,成为一个具有显著突破意义和应用前景的研究领域。The process of high-harmonic generation is a mature and feasible plan to build coherent quantum light sources.It is widely used in the emerging X-ray quantum optical field and is expected for its deep application.X-ray is theoretically proved better than the currently widely used microwave and visible light band due to its high precision,high diffraction limit,robustness,penetration and focusing ability.Developing quantum optical models,quantum information units and quantum optical components in X-ray bands,could help to their promote precision and miniaturize development.Recent research combines quantum optics with X-ray,producing new types of light sources such as X-ray free electronic lasers,quantum systems,single photon,pulse,and high harmonic generation of coherent quantum light resource under the X-ray regime.The cross between X-ray optics and quantum optics is attracting more and more attention from researchers,becoming a research field with significant breakthroughs and application prospects.The atomic system used in X-ray frequency band quantum optical experiments is the Fe Mossbauer nuclear ensemble,because it has narrow nuclear resonance width narrow(4.7 neV)and long coherence time due to its abundance of cooperative effects.In recent years,researchers have achieved the proof of spontaneous generation coherence under the ensemble,as well as the multi-layer nuclear ensemble model scheme with strong coupling properties.On the other hand,researchers have achieved multiple paths of maintaining the transition in X-ray nuclei such as electromagnetic induced transparency,acoustic induced transparency,and optomechanically induced transparency.In the past five years,the methods above have been optimized,filling the gap in the regulation of X-ray quantum system.X-ray quantum optics requires high-quality X-ray light sources.At present,the scheme of super-fine magnetic field regulation single photon storage has achieved energy and phase storage.In addition,the waveform modulation of X-ray single photon mainly adop
