Illumination-induced nonequilibrium charge states in self-assembled quantum dots
Sascha R. Valentin, Jonathan Schwinger, Pia Eickelmann +4
We report on capacitance-voltage spectroscopy of self-assembled InAs quantum dots under constant illumination. Besides the electronic and excitonic charging peaks in the spectrum r…
A single eletron-photon pair generation from a single polarization-entangled photon pair
Kazuyuki Kuroyama, Marcus Larsson, Sadashige Matsuo +6
We demonstrate paired generation of a single photo-electron in a quantum dot and a single photon from a single polarization-entangled photon pair that is generated by spontaneous p…
Optical nanoscopy via quantum control
Timo Kaldewey, Andreas V. Kuhlmann, Sascha R. Valentin +3
We present a scheme for nanoscopic imaging of a quantum mechanical two-level system using an optical probe in the far-field. Existing super-resolution schemes require more than two…
Coherent and robust high-fidelity generation of a biexciton in a quantum dot by rapid adiabatic passage
Timo Kaldewey, Sebastian Lüker, Andreas V. Kuhlmann +6
A biexciton in a semiconductor quantum dot is a source of polarization-entangled photons with high potential for implementation in scalable systems. Several approaches for non-reso…
Demonstrating the decoupling regime of the electron-phonon interaction in a quantum dot using chirped optical excitation
Timo Kaldewey, Sebastian Lüker, Andreas V. Kuhlmann +7
Excitation of a semiconductor quantum dot with a chirped laser pulse allows excitons to be created by rapid adiabatic passage. In quantum dots this process can be greatly hindered…
