摘要
Point defect qubits in semiconductors have demonstrated their outstanding capabilities for high spatial resolution sensing generating broad multidisciplinary interest.Hexagonal boron nitride(hBN)hosting point defect qubits have recently opened up new horizons for quantum sensing by implementing sensing foils.The sensitivity of point defect sensors in hBN is currently limited by the linewidth of the magnetic resonance signal,which is broadened due to strong hyperfine couplings.
