摘　　要：随着X射线光源品质的提升,X射线波段的量子调控成为了新兴的前沿领域,基于薄膜平面腔的X射线腔量子光学是其中一个重要分支.X射线腔量子光学研究始于原子核跃迁体系,近期兴起了调控原子内壳层跃迁的研究工作.原子内壳层跃迁存在丰富的候选体系和退激通道,极大地拓宽了X射线腔量子光学的研究范围.此外,内壳层激发及其退激通道对应着多种X射线谱学表征技术,促进X射线腔量子光学和谱学技术的融合,有望促成X射线谱学新技术的出现.本文概述了基于原子内壳层跃迁的X射线腔量子光学,介绍了基本的实验体系和实验方法、经典和量子理论模型以及已经实现的一些量子光学现象.最后,本文简要介绍了内壳层X射线腔量子光学仍需要解决的一些问题,同时展望了未来的发展方向.Over the past decade,X-ray quantum optics has emerged as a dynamic research field,driven by significant advancements in X-ray sources such as next-generation synchrotron radiation facilities and X-ray free-electron lasers,as well as improvements in X-ray methodologies and sample fabrication techniques.One of the most successful platforms in this field is the X-ray planar thin-film cavity,also known as the X-ray cavity QED setup.To date,most studies in X-ray cavity quantum optics have focused on Mössbauer nuclear resonances.However,this approach is constrained by the limited availability of suitable nuclear isotopes and the lack of universal applicability.Recently,experimental realizations of X-ray cavity quantum control in atomic innershell transitions have demonstrated that cavity effects can simultaneously modify transition energies and corehole lifetimes.These pioneering studies suggest that X-ray cavity quantum optics based on inner-shell transitions will become a promising new platform.Notably,the core-hole state is a fundamental concept in various modern X-ray spectroscopic techniques.Therefore,integrating X-ray quantum optics with X-ray spectroscopy holds the potential to open new frontiers in the field of core-level spectroscopy.In this review,we introduce the experimental systems used in X-ray cavity quantum optics with inner-shell transitions,covering cavity structures,sample fabrications,and experimental methodologies.We explain that X-ray thin-film cavity experiments require high flux,high energy resolution,minimal beam divergence,and precise angular control,necessitating the use of synchrotron radiations.Grazing reflectivity and fluorescence measurements are described in detail,along with a brief introduction to resonant inelastic X-ray scattering techniques.The review also outlines simulation tools,including the classical Parratt algorithm,semi-classical matrix formalism,quantum optical theory based on the Jaynes-Cummings model,and the quantum Green’s function method.We discuss the similarities a
