Hexagonal boron nitride (hBN) has emerged as a fascinating platform to explore quantum emitters and their applications. Beyond being a wide-bandgap material, it is also a van der Waals crystal, enabling direct exfoliation of atomically thin layers─a combination which offers unique advantages over bulk, 3D crystals. In this Mini Review we discuss the unique properties of hBN quantum emitters and highlight progress toward their future implementation in practical devices. We focus on engineering and integration of the emitters with scalable photonic resonators. We also highlight recently discovered spin defects in hBN and discuss their potential utility for quantum sensing. All in all, hBN has become a front runner in explorations of solid-state quantum science with promising future prospects.

六方氮化硼中的量子发射体

六方氮化硼 (hBN) 已成为探索量子发射器及其应用的迷人平台。除了是一种宽带隙材料，它还是一种范德瓦尔斯晶体，可以直接剥离原子级薄层——这种组合与块状 3D 晶体相比具有独特的优势。在这篇 Mini Review 中，我们讨论了 hBN 量子发射器的独特特性，并强调了它们未来在实际设备中的应用进展。我们专注于发射器与可扩展光子谐振器的工程和集成。我们还重点介绍了最近在 hBN 中发现的自旋缺陷，并讨论了它们在量子传感方面的潜在用途。总而言之，hBN已成为固态量子科学探索的领跑者，前景广阔。
