Single Photon emitters are a crucial resource for novel photonic quantum technologies. Quantum emitters hosted in two-dimensional hexagonal Boron Nitride (hBN) are a promising candidate for the integration into hybrid quantum systems. One type of emitters hosted in hBN has shown the remarkable property of Fourier limited linewidths from cryogenic up to room temperatures. This property can be attributed to mechanically isolated orbitals of the defect centers, which do not couple to in-plane phonon modes. Here, we present our recent results towards identifying the origin of this mechanical decoupling, which could be caused by out-of-plane emitters. We also present quantum random number generation using the symmetric dipole emission profile of these emitters.
