Atomic vapor-based turnstile device for single photons

Project description

Rubidium atoms could make single-photon sources

Single-photon sources with Fourier transform limited lines are deemed promising for use in photonic quantum technologies. Such sources rely on resonant light–atom interactions within an ensemble of weakly coupled emitters. Quantum interference can modify the photon statistics of weak coherent states when travelling through the ensemble. This quantum interference mechanism has been recently demonstrated with cold atoms. When interacting with a certain number of emitters, the coherent states can be transformed into streams of single photons. Funded by the Marie Skłodowska-Curie Actions programme, the AVATURN project aims to use rubidium atomic vapour instead of cold atoms. This could lead to the development of single-photon sources that eliminate the need for cryogenic environments.
