A limitation of optical quantum technologies is the probabilistic operation of two quantum bit gates. To develop deterministic photon-photon gates, optical nonlinearities at the level of a single photon are needed.

The spin of a carrier trapped in a quantum dot can store quantum information over microseconds. By inserting such a spin in an optical cavity, we have built an efficient interface between this spin stationary qubit and a photon.
