Polarization-entangled twin photons from two-photon quantum-dot emission
Dirk Heinze, Artur Zrenner, Stefan Schumacher
Semiconductor quantum dots are promising sources for polarization-entangled photons. As an alternative to the usual cascaded biexciton-exciton emission, direct two-photon emission…
All-optical tailoring of single-photon spectra in a quantum-dot microcavity system
Dominik Breddermann, Dirk Heinze, Rolf Binder +2
Semiconductor quantum-dot cavity systems are promising sources for solid-state based on-demand generation of single photons for quantum communication. Commonly, the spectral charac…
A quantum dot single-photon source with on-the-fly all-optical polarization control and timed emission
Dirk Heinze, Artur Zrenner, Stefan Schumacher
Sources of single photons are key elements in the study of basic quantum optical concepts and applications in quantum information science. Among the different sources available, se…
Recent advances in exciton based quantum information processing in quantum dot nanostructures
H. J. Krenner, S. Stufler, M. Sabathil +6
Recent experimental developments in the field of semiconductor quantum dot spectroscopy will be discussed. First we report about single quantum dot exciton two-level systems and th…
Optical excitations of a self assembled artificial ion
F. Findeis, M. Baier, A. Zrenner +4
By use of magneto-photoluminescence spectroscopy we demonstrate bias controlled single-electron charging of a single quantum dot. Neutral, single, and double charged excitons are i…
