Decoherence of V $${}_{{{{{{{{\rm{B}}}}}}}}}^{-}$$ B − spin defects in monoisotopic hexagonal boron nitride

Abstract

Recently, coherent control of spin defects in hBN has been realized, enabling future applications in quantum sensing technologies. Here the authors perform a systematic study of isotope-dependent spin coherence properties of the negatively-charged boron-vacancy defect in monoisotopic hBN crystals.
