Quantum Optics Colloquium by Søren Stobbe

Semiconductor quantum dots are nanoscale objects with discrete electronic states and they are excellent single-photon emitters. Their solid-state nature give them a number of advantages over atomic emitters, in particular in being naturally localized in space and because sophisticated optoelectronic nanostructures may be built around them using semiconductor nanotechnology. However, the same solid-state environment gives rise to a
number of challenges, e.g., decoherence due to the influence of charge fluctuations, nuclear spin noise, and phonons. In this talk, I will give an introduction to quantum dots and their integration in photonic nanostructures and discuss research challenges and current directions for quantum photonics with quantum dots, in particular towards highly efficient single-photon sources for photonic quantum simulation.
