摘要 (Abstract)：

In this presentation I will showcase our journey in discovering and engineering new quantum phenomena in hBN over the past decade. Solid state materials are reliable and harbour favourable properties, it is the fundamental cornerstone for quantum-based technologies. Hexagonal Boron Nitride (hBN) is capable of hosting atomic defects which can emit high-purity single-photons at room temperature. Single photon sources (SPS) are integrated in nanophotonics and is optimized via various fabrication methods to increase the signal-to-noise ratio and combat the problem of collection efficiency and demonstrate how it can be utilised for practical quantum technologies such as sharing secure keys over long distances through fiber or free space networks, to distribute entanglement for connecting quantum computers together, or even to perform the quantum computation directly.
