Abstract [en]
Hexagonal boron nitride (hBN) has recently gained attention as a solid state host of quantum emitters. In particular, the recently discovered B centers show promise for integration in scalable quantum technologies thanks to site-specific defect generation and a reproducible wavelength. Here we employ spectral hole burning spectroscopy and resonant polarization measurements to observe nearly coherent hBN quantum emitters, both as singles and in ensembles, with three discrete polarization axes indicative of a C (2v) symmetry defect. Our results constitute an important milestone toward the implementation of hBN quantum emitters in integrated quantum photonics.
