The PhD work consists in building an efficient interface between a single material qubit (the spin of a single charge, confined in an InAs/GaAs quantum dot) and a single photonic qubit (the polarization of a single photon). The quantum dot is deterministically coupled to an electrically-contacted pillar microcavity: such technology invented in C2N has already allowed developing high-efficiency sources of quantum light, and demonstrating the first optical nonlinearity reaching the single-photon level.

As recently demonstrated, a photon reflected by such a QD-cavity structure can experience a drastically-enhanced and spin-dependant rotation of its polarization, which allows mapping the spin quantum state onto a photonic polarization state. In this thesis, we will explore the numerous perspectives of such a spin-photon interface for quantum information.
