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…
Signatures of the Optical Stark Effect on Entangled Photon Pairs from Resonantly-Pumped Quantum Dots
Francesco Basso Basset, Michele B. Rota, Mattia Beccaceci +12
Two-photon resonant excitation of the biexciton-exciton cascade in a quantum dot generates highly polarization-entangled photon pairs in a near-deterministic way. However, the ulti…
Linear colossal magnetoresistance driven by magnetic textures in LaTiO3 thin films on SrTiO3
Teresa Tschirner, Berengar Leikert, Felix Kern +12
Linear magnetoresistance (LMR) is of particular interest for memory, electronics, and sensing applications, especially when it does not saturate over a wide range of magnetic field…
Optical properties of circular Bragg gratings with labyrinth geometry to enable electrical contacts
Quirin Buchinger, Simon Betzold, Sven Höfling +1
We present an optical study of various device designs for electrically contactable circular Bragg grating cavities in labyrinth geometries. To create an electrical connection betwe…
Optically driven rotation of exciton-polariton condensates
Yago del Valle Inclan Redondo, Christian Schneider, Sebastian Klembt +3
The rotational response of quantum condensed fluids is strikingly distinct from rotating classical fluids, especially notable for the excitation and ordering of quantized vortex en…
Voltage control of the quantum scattering time in InAs/GaSb/InAs trilayer quantum wells
M. Meyer, S. Schmid, F. Jabeen +3
We study the evolution of the quantum scattering time by gate voltage training in the topological insulator based on InAs/GaSb/InAs trilayer quantum wells. Depending on the minimal…
Deep learning of quantum entanglement from incomplete measurements
Dominik Koutný, Laia Ginés, Magdalena Moczała-Dusanowska +4
The quantification of the entanglement present in a physical system is of para\-mount importance for fundamental research and many cutting-edge applications. Currently, achieving t…
Numerical optimization of single-mode fiber-coupled single-photon sources based on semiconductor quantum dots
Lucas Bremer, Carlos Jimenez, Simon Thiele +8
We perform extended numerical studies to maximize the overall photon coupling efficiency of fiber-coupled quantum dot single-photon sources emitting in the near-infrared and teleco…
All-optical Tuning of Indistinguishable Single-Photons Generated in Three-level Quantum Systems
Łukasz Dusanowski, Chris Gustin, Stephen Hughes +2
Resonance fluorescence of two-level quantum systems has emerged as a powerful tool in quantum information processing. Extension of this approach to higher-level systems provides ne…
