Entanglement Swapping with Semiconductor-generated Photons
Michael Zopf, Robert Keil, Yan Chen +4
Transferring entangled states between photon pairs is essential for quantum communication technologies. Semiconductor quantum dots are the most promising candidate for generating p…
Frequency Feedback for Two-Photon Interference from Separate Quantum Dots
Michael Zopf, Tobias Macha, Robert Keil +7
We employ active feedback to stabilize the frequency of single photons emitted by two separate quantum dots to an atomic standard. The transmission of a single, rubidium-based Fara…
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…
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…
