  • The authors report an experiment demonstrating fast control of the quantum dot–cavity coupling, indicating the coherent transfer of photons between the cavity and the quantum dot.

  • Cup-shaped molecules of calix[4]hydroquinone self-assemble on a surface into a lens shape; these lenses are shown to generate near-field magnification beyond the diffraction limit, enabling the resolution of features of the order of 200 nanometres. Such spherical nanolenses provide new pathways for lens-based near-field focusing and high-resolution optical imaging at very low intensities, which are useful for, among other things, bio-imaging and near-field lithography.

  • Researchers realize a quantum logic gate by performing all-optical coherent control of the exciton states of an InAs quantum dot in a photonic crystal cavity in the strong-coupling regime. Their demonstrations represent an important step towards realizing robust and scalable quantum networks and generating strong photon-photon interactions.
