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…
A machine learning approach to drawing phase diagrams of topological lasing modes
Stephan Wong, Jan Olthaus, Thomas K. Bracht +2
Identifying phases and analyzing the stability of dynamic states are ubiquitous and important problems which appear in various physical systems. Nonetheless, drawing a phase diagra…
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…
SUPER Scheme in Action: Experimental Demonstration of Red-detuned Excitation of a Quantum Dot
Yusuf Karli, Florian Kappe, Vikas Remesh +8
The quest for the perfect single-photon source includes finding the optimal protocol for exciting the quantum emitter. Based on a recently proposed, so-called SUPER (swing-up of qu…
Phonon wave packet emission during state preparation of a semiconductor quantum dot using different schemes
Thomas K. Bracht, Tim Seidelmann, Tilmann Kuhn +2
The carrier-phonon interaction in semiconductor quantum dots can greatly affect the optical preparation of the excited state. For resonant excitation used in the Rabi preparation s…
