Solid state sources of single photons ("quantum emitters") are a key building block for implementation of scalable quantum technologies. Amongst many potential platforms studied, impurities in hexagonal boron nitride (hBN) are at the forefront due to their brightness and ease of manufacturing. However, their main disadvantage is spectral instability which prohibits engineering of practical devices. The current project will address this bottleneck and deliver an optically stable solid state quantum light source in hBN. The project will produce a robust hardware toolkit for quantum technologies. It will provide excellent training for young Australians and generate key intellectual property for quantum startups and the quantum industry.Read moreRead less
