Solid-state ensemble of highly entangled photon sources at rubidium atomic transitions
Robert Keil, Michael Zopf, Yan Chen +4
Semiconductor InAs/GaAs quantum dots grown by the Stranski-Krastanov method are among the leading candidates for the deterministic generation of polarization entangled photon pairs…
Hanbury Brown and Twiss anticorrelation in disordered photonic lattices
H. Esat Kondakci, Lane Martin, Robert Keil +5
We report measurements of Hanbury Brown and Twiss correlation of coherent light transmitted through disordered one-dimensional photonic lattices. Although such a lattice exhibits t…
Hybrid waveguide-bulk multi-path interferometer with switchable amplitude and phase
Robert Keil, Thomas Kaufmann, Thomas Kauten +5
We design and realise a hybrid interferometer consisting of three paths based on integrated as well as on bulk optical components. This hybrid construction offers a good compromise…
Many-body quantum interference on hypercubes
Christoph Dittel, Robert Keil, Gregor Weihs
Beyond the regime of distinguishable particles, many-body quantum interferences influence quantum transport in an intricate manner. However, symmetries of the single-particle trans…
Electric-field-induced energy tuning of on-demand entangled-photon emission from self-assembled quantum dots
Jiaxiang Zhang, Eugenio Zallo, Bianca Höfer +6
The scalability of quantum dot based non-classical light sources relies on the control over their dissimilar emission energies. Electric fields offer a promising route to tune the…
