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…
A source of entangled photons based on a cavity-enhanced and strain-tuned GaAs quantum dot
Michele B. Rota, Tobias M. Krieger, Quirin Buchinger +21
A quantum-light source that delivers photons with a high brightness and a high degree of entanglement is fundamental for the development of efficient entanglement-based quantum-key…
Nuclear spin diffusion in the central spin system of a GaAs/AlGaAs quantum dot
Peter Millington-Hotze, Santanu Manna, Saimon F. Covre da Silva +2
The spin diffusion concept provides a classical description of a purely quantum-mechanical evolution in inhomogeneously polarized many-body systems such as nuclear spin lattices. T…
Ideal refocusing of an optically active spin qubit under strong hyperfine interactions
Leon Zaporski, Noah Shofer, Jonathan H. Bodey +15
Combining highly coherent spin control with efficient light-matter coupling offers great opportunities for quantum communication and networks, as well as quantum computing. Optical…
Fast and efficient demultiplexing of single photons from a quantum dot with resonantly enhanced electro-optic modulators
Julian Münzberg, Franz Draxl, Saimon Filipe Covre da Silva +5
We report on a multi-photon source based on active demultiplexing of single photons emitted from a resonantly excited GaAs quantum dot. Active temporal-to-spatial mode demultipexin…
Surface passivation and oxide encapsulation to improve optical properties of a single GaAs quantum dot close to the surface
Santanu Manna, Huiying Huang, Saimon Filipe Covre da Silva +6
Epitaxial GaAs quantum dots grown by droplet etching have recently shown excellent properties as sources of single photons as well as entangled photon pairs. Integration in some na…
