Controlling the charge environment of single quantum dots in a photonic-crystal cavity
LL-3: Semiconductor quantum dots (QDs) allow solid-state implementations of cavity quantum electrodynamics, with application to single photon sources, entanglement generation, and quantum computing. However, micro-photoluminescence of QDs coupled to optical microcavities reveals a phenomenon contradicting the ideal atom-in-a-cavity model. We explain this and show experimentally that the application of an electric field brings the system closer to an ideal two-level system. This has applications for QDs in quantum information processing, e.g. improving the purity of single-photon sources. Subsequently a new research collaboration between Eindhoven and Leeds was established leading to four further primary archival papers.
