Semiconductor quantum dots for integrated quantum optics

Electronic excitations in strain-free III-V semiconductor quantum dots are very good candidates to address single quantum bits, coherently controlled by optical pulses. Studying the non-linear interaction between carriers and the nuclear spin bath will allow controlling the nuclear magnetization dynamics and generate a self-oscillating spin mode at the nanoscale. The goal is to realize a robust spin-photon interface by controlling the environment, particularly the magnetic one and demonstrate entanglement between distant spins.
