TRR 142 - Ultrafast coherent opto-electronic control of a photonic quantum system (B06*)
Overview
In this project we will integrate semiconductor quantum dots in field-tunable microcavity heterostructures to achieve ultrafast coherent opto-electronic control of the emitter cavity coupling. By tuning different quantum dot transitions in and out of the cavity resonance we aim to generate (i) cavity assisted two-photon emission, (ii) hyper entangled photon states, as well as (iii) syncronization of the emission of remote quantum emitters. Our approach will enable the realization of scalable single-photon and photon-pair sources with almost ideal properties of the emitted photons.
