摘　　要：腔光力系统作为一种新型的混合量子系统,因其超强耦合度、低温超导条件下极低的噪声、较长的相干时间等优势而成为被广受关注的量子实验平台.本文简要介绍腔光力学及腔光力系统基本原理,对常见腔光力系统进行分类,详细介绍利用广义腔光力系统进行微波非经典量子态制备的相关进展,对其性能优势和待解决问题进行分析,最后总结相关应用场景并对未来的潜在应用领域进行了展望.As a novel hybrid quantum system, cavity optomechanical system shows super strong coupling strength,extremely low noise level and considerable coherent time under superconducting condition. In this paper, we briefly introduce basic principles of cavity optomechanics and cavity optomechanical systems. Meanwhile, we also classify the widely studied cavity optomechanical systems as five categories in their materials and structures. Significant parameters of these optomechanical systems, such as quality factor, mass and vibrating frequency of mechanical oscillator, are listed in detail. Technical merits and defects of these optomechanical systems are summarized. Furthermore, we introduce the research progress of non-classical microwave quantum states preparation by utilizing generalized cavity optomechanical systems, and we also analyze the performance advancements and remaining problems of this preparation method. In the end, we summarize the application cases at present and look forward to the potential application scenarios in the future. Our summary may be helpful for researchers who are focusing on quantum applications in sensing, radar, navigation, and communication in microwave domain.
