  • The Josephson effects that arise when two quantum states are coupled through a barrier are difficult to observe in optical systems because photon–photon interactions are so weak. Researchers have now demonstrated an optical realization of two such phenomena—macroscopic self-trapping and Josephson oscillations—using polariton condensates in overlapping microcavities.

  • Carbon-related point defects can be isolated in a commercial silicon-on-insulator wafer, acting as artificial atoms that provide efficient polarized single-photon emission at wavelengths suitable for long-distance propagation in optical fibres.
