Hybrid Atomic-Solid State Systems

Artistic view of a single quantum dot and an Rb vapor

We combine single quantum dots and warm rubidium vapors. This is made possible with high quality quantum dots made of GaAs in a AlGaAs matrix that emit close the transition frequency of rubidium (D2 lines). We have slowed down single photons emitted by a single quantum dot in an atomic vapor. Another possible experiment is the realization of a quantum memory where single photons from a quantum dot could be stored in an atomic ensemble.
