  • This work shows how to connect a fibre to a single-photon source based on quantum dots in microcavities. The alignment relies on reflectivity measurements. The structure is stable from room to cryogenic temperature and over several cooling cycles.

  • A versatile cloud-accessible single-photon-based quantum computing machine is developed, which shows a six-photon sampling rate of 4 Hz over weeks. Heralded generation of a three-photon Greenberger–Horne–Zeilinger state—a key milestone toward measurement-based quantum computing—is implemented.

  • A photon-number Bell state is generated from a quantum dot by controlling the light–matter entanglement during spontaneous emission. This excitation protocol can be scaled up by using N consecutive π-pulses to deliver multimode photonic entanglement.

  • The energy interaction between different exciton species is affected by the optical environment in which they are embedded. It is now shown that mixed exciton–polariton states in strongly coupled microcavities can facilitate energy transfer between organic dyes at length scales greater than the Förster transfer radius.

  • An optical non-linearity at the single-photon level is reported with a semiconductor quantum dot–cavity device. The device performs as an efficient single-photon filter that strongly suppresses the multiphoton components of incident coherent pulses.
