Theory of time-bin entangled photons from quantum emitters
Thomas K. Bracht, Florian Kappe, Moritz Cygorek +6
Entangled photon pairs form the foundation for many applications in the realm of quantum communication. For fiber-optic transfer of entangled photon pairs, time-bin encoding can po…
Temperature-independent almost perfect photon entanglement from quantum dots via the SUPER scheme
Thomas K. Bracht, Moritz Cygorek, Tim Seidelmann +2
Entangled photon pairs are essential for quantum communication technology. They can be generated on-demand by semiconductor quantum dots, but several mechanisms are known to reduce…
Beyond the four-level model: Dark and hot states in quantum dots degrade photonic entanglement
Barbara Ursula Lehner, Tim Seidelmann, Gabriel Undeutsch +9
Entangled photon pairs are essential for a multitude of photonic quantum applications. To date, the best performing solid-state quantum emitters of entangled photons are semiconduc…
Dressed-state analysis of two-color excitation schemes
Thomas K. Bracht, Tim Seidelmann, Yusuf Karli +5
To coherently control a few-level quantum emitter, typically pulses with an energy resonant to the transition energy are applied making use of the Rabi mechanism, while a single of…
Collective Excitation of Spatio-Spectrally Distinct Quantum Dots Enabled by Chirped Pulses
Florian Kappe, Yusuf Karli, Thomas K. Bracht +7
For a scalable photonic device producing entangled photons, it is desirable to have multiple quantum emitters in an ensemble that can be collectively excited, despite their spectra…
Two-Photon Excitation Sets Limit to Entangled Photon Pair Generation from Quantum Emitters
Tim Seidelmann, Christian Schimpf, Thomas K. Bracht +5
Entangled photon pairs are key to many novel applications in quantum technologies. Semiconductor quantum dots can be used as sources of on-demand, highly entangled photons. The fid…
