  • Producing isolated single-photon emitters in hexagonal boron nitride with predefined spin transitions is challenging. Oxygen annealing enables the controlled fabrication of narrowband quantum emitters with optically active spin for quantum applications.

  • Optical spin defects in semiconductors are crucial for applications, but it is often difficult to establish their microscopic origin. A mechanism for the spin behaviour of a family of bright emitters in hexagonal boron nitride has now been identified.

  • Nitrogen vacancy centres can be used for nanoscale nuclear magnetic resonance detection but this typically involves strong microwave control pulses, making practical realizations difficult. Here the authors demonstrate a microwave-free spectroscopic protocol that can detect spins in external samples.

  • The 2D material hBN hosts various optically addressable spin defects, promising for quantum technology applications. Here the authors report the co-existence of spin-1 and spin-1/2 defects in hBN, show their room temperature coherent control and optical readout, as well as cross-relaxation.

  • Some material defects have quantum degrees of freedom that are measurably disturbed by environmental changes, making them excellent sensors. A two-dimensional material with such defects could improve the versatility of quantum-sensing technologies.

  • Hexagonal boron nitride is a common component of 2D heterostructures. Defects implanted in boron nitride crystals can be used to perform spatially resolved sensing of properties, including temperature, magnetism and current.

  • Molecules with ‘hyperpolarised’ nuclear spins can be used to improve MRI performance but require an efficient polarisation method. Broadway et al. demonstrate a quantum control protocol using a nitrogen vacancy centre inside a diamond to hyperpolarise protons within molecules deposited on the surface.
