Room temperature optically detected magnetic resonance of single spins in GaN
Optically detected magnetic resonance (ODMR) is an efficient mechanism for quantum sensors and has been discovered in a few systems, but all have technological limitations. Here the authors report room temperature ODMR in single defects in GaN, promising for integrated quantum sensing applications.

Fabrication and nanophotonic waveguide integration of silicon carbide colour centres with preserved spin-optical coherence
Colour centres are a promising quantum information platform, but coherence degradation after integration in nanostructures has hindered scalability. Here, the authors show that waveguide-integrated VSi centres in SiC maintain spin-optical coherences, enabling nuclear high-fidelity spin qubit operations.

Towards polariton blockade of confined exciton–polaritons
Confined exciton–polaritons in semiconductor-based quantum wells can give rise to correlations slightly below the level of classical coincidence counts under resonant excitation, such that single or few polariton excitations are sufficient to modify the statistics of the radiation going through the system.

Asymmetrically strained quantum dots with non-fluctuating single-dot emission spectra and subthermal room-temperature linewidths
Asymmetric strain intrinsic to core/shell nanocrystals based on lattice-mismatched wurtzite semiconductors leads to suppression of spectral fluctuation, narrowing of photoluminescence linewidth and reduced blinking in colloidal nanocrystals.
