  • Previously, superradiance was observed from sizeable crystals or close to liquid-helium temperatures. Here, Bradec et al. report the observation of room-temperature superradiance from single, highly luminescent diamond nanocrystals with spatial dimensions much smaller than the wavelength of light.

  • The photophysical properties of quantum emitters in layered van der Waals materials are receiving growing attention as they could be leveraged for nanophotonics applications. Here, the authors devise a two-laser super-resolution imaging setup capable of observing highly non-linear emission from hBN emitters.

  • Diamond colour centres have applications in quantum sensing, quantum communication and other important technologies. Bradac et al. survey the progress made in using group IV defect centres, which are anticipated to have practical advantages over the more commonly-used nitrogen vacancy centres.

  • Direct writing of active defects is a much sought-after step towards scalable quantum technologies. Here, the authors show a flexible approach by transferring momentum from an ion beam to thin films pre-deposited onto diamond surfaces (using films of Si, Ge, Sn or Pb) or fiber cores (using Eu).

  • The strength of optical trapping of a nanodiamond can be increased by cooperative effects between its numerous colour centres — or artificial atoms: an observation that brings together ideas from atom and nanoparticle trapping.

  • Spin defects in two-dimensional materials potentially offer unique advantages for quantum sensing in terms of sensitivity and functionality. Here, the authors demonstrate the use of spin defects in hexagonal boron nitride as sensors of magnetic field, temperature and pressure, and show that their performance is comparable or exceeds that of existing platforms.
