  • Isotope engineering can enhance spin coherence of solid-state defects, such as NV centers in diamond but progress for defects in hBN has been limited. Gong et al. report the optimization of isotopes in hBN and demonstrate improved coherence and relaxation times for the negatively charged boron vacancy centers.

  • Spin defects in 2D materials offer practical advantages for quantum sensing over their 3D counterparts. Here, the authors demonstrate quantum sensing under high pressure using boron vacancy centers in hBN placed inside a diamond anvil cell and use it to detect both stress gradient inside the pressure chamber and pressure-induced magnetic phase transitions.

  • The boron vacancy center in hBN has been intensively studied, but its characterizations have remained limited. Here the authors achieve a 5-fold enhancement of coherence time using dynamical decoupling, which enables the direct estimation of defect concentration and its electric field susceptibility.
