AI 中文摘要
经典上，望远镜的角分辨率受限于其衍射极限：即观测波长与直径之比。过去十年中，量子信息理论的发展揭示了能够超越衍射极限实现超分辨成像的量子最优测量方法，并且过去十年间已进行了许多实验室规模的演示，最终在近期首次实现了量子增强天文成像的实地观测。在这篇综述中，我们详细介绍了这些理论和实验结果的当前进展与成就，讨论了推动更高分辨率望远镜发展的天文科学案例，总结了量子成像技术实际应用于天文学所面临的技术挑战，并展望了实现成像分辨率比现有天文台高出数个数量级的“量子望远镜”的愿景。
英文摘要
Classically, the angular resolution of a telescope is limited by its diffraction limit: the ratio of its observing wavelength to its diameter. Developments in quantum information theory over the past decade have uncovered quantum-optimal measurement methods that enable super-resolution imaging beyond the diffraction limit, and many laboratory-scale demonstrations of these methods have been performed over the past decade, culminating in the recent first on-sky demonstration of quantum-enhanced astronomical imaging. In this Review, we detail the current progress and achievements of these theoretical and experimental results, discuss the astronomical science cases motivating the development of higher resolution telescopes, summarise the technological challenges facing the practical application of quantum imaging technologies to astronomy, and present a vision for the realization of \emph{quantum telescopes} with imaging resolutions orders of magnitude better than current observatories.
