Hexagonal boron nitride (hBN) has emerged as a solid-state platform for hosting a variety of defects for quantum applications. Identifying optimal defects for specific quantum applications has been challenging as some defects exhibit similar properties while others encounter strain. Comprehensive properties are therefore required. This work addresses this gap by utilizing density functional theory and open quantum system approaches to thoroughly characterize the properties of 257 defects and evaluate their potential for quantum emitter and quantum memory applications. This enables matching defects with suitable quantum applications. Furthermore, all findings are compiled into an accessible online database at https://h-bn.info, allowing one to compare our calculated optical fingerprints with experiments and other simulations. Consequently, this work enriches hBN defect resources, supporting progress in quantum technologies and defect identification.
