Quantum black holes, a broad class of objects that refine the solutions of general relativity by incorporating semiclassical and/or quantum gravitational effects, have recently attracted renewed attention within the scientific community. This resurgence of interest is largely driven by advances in gravitational wave astronomy, which have opened the possibility of testing some of these models in the near future. In this essay, we provide a concise overview of the key discussions that emerged during the “Black Hole Inside/Out" meeting, held in August 2024 in Copenhagen. We report these ideas, their connections to the information paradox, and the potential use of analogue gravity as a test bed for these concepts.

量子黑洞是一类广泛的天体，通过结合半经典和/或量子引力效应来改进广义相对论的解，最近在科学界重新引起了关注。这种兴趣的重新抬头主要是由引力波天文学的进步推动的，这为在不久的将来测试其中一些模型提供了可能性。在本文中，我们简要概述了 2024 年 8 月在哥本哈根举行的 “黑洞内/外 ”会议期间出现的关键讨论。我们报告了这些想法，它们与信息悖论的联系，以及模拟引力作为这些概念的试验台的潜在用途。
