Holographic quantum matter exhibits an intriguing connection between quantum black holes and more conventional (albeit strongly interacting) quantum many-body systems. This connection is manifested in the study of their thermodynamics, statistical mechanics and many-body quantum chaos. In this Review, we discuss these connections, focusing on the most promising example of holographic quantum systems to date – the family of Sachdev–Ye–Kitaev (SYK) models. The SYK models are simple quantum mechanical models that have the potential to holographically realize quantum black holes. We examine various proposals for the experimental realizations of SYK models, including ultracold gases, graphene flakes, semiconductor quantum wires and 3D topological insulators. These approaches offer the exciting prospect of accessing black hole physics and thus addressing many important questions regarding quantum gravity in the laboratory.

全息量子物质在量子黑洞与更传统的（尽管相互作用很强）量子多体系统之间表现出令人着迷的联系。这种联系在对他们的热力学，统计力学和多体量子混沌的研究中得到了体现。在本综述中，我们将讨论这些联系，重点是迄今为止最有希望的全息量子系统示例-Sachdev-Ye-Kitaev（SYK）模型家族。SYK模型是简单的量子力学模型，具有全息实现量子黑洞的潜力。我们研究了SYK模型的实验实现的各种建议，包括超冷气体，石墨烯薄片，半导体量子线和3D拓扑绝缘体。
