Deterministic Control of Photon-Number Probabilities via Phase-Controlled Quantum Interference
Sang Kyu Kim, Eduardo Zubizarreta Casalengua, Yeji Sim +8
Deterministically tailoring optical Fock states beyond the single-photon level is crucial for boson sampling, loss-tolerant photonic qubits, and quantum-enhanced sensing, however h…
Selective filtering of multi-photon events from a single-photon emitter
Friedrich Sbresny, Carolin Calcagno, Sang Kyu Kim +7
Single-photon purity is one of the most important key metrics of many quantum states of light. For applications in photonic quantum technologies, e.g. quantum communication and lin…
Dynamically Dressed States of a Quantum Four-Level System
Carolin Calcagno, Friedrich Sbresny, Thomas K. Bracht +8
In this work, we experimentally and theoretically study the dressed-state emission of the biexciton-exciton cascade in a semiconductor quantum dot under pulsed, resonant, two-photo…
Unlocking multiphoton emission from a single-photon source through mean-field engineering
Sang Kyu Kim, Eduardo Zubizarreta Casalengua, Katarina Boos +9
Single-photon emission from a two-level system offers promising perspectives for the development of quantum technologies, where multiphotons are generally regarded as accidental, u…
Unveiling the interplay of Mollow physics and perturbed free induction decay by nonlinear optical signals of a dynamically driven two-level system
Jan M. Kaspari, Thomas K. Bracht, Katarina Boos +4
Nonlinear optical signals in optically driven quantum systems can reveal coherences and thereby open up the possibility for manipulation of quantum states. While the limiting cases…
Signatures of dynamically dressed states
Katarina Boos, Sang Kyu Kim, Thomas Bracht +10
The interaction of a resonant light field with a quantum two-level system is of key interest both for fundamental quantum optics and quantum technological applications employing re…
Magnetic tuning of the tunnel coupling in an optically active quantum dot molecule
Frederik Bopp, Charlotte Cullip, Christopher Thalacker +15
Self-assembled optically active quantum dot molecules (QDMs) allow the creation of protected qubits via singlet-triplet spin states. The qubit energy splitting of these states is d…
Coherent driving of direct and indirect excitons in a quantum dot molecule
Frederik Bopp, Johannes Schall, Nikolai Bart +13
Quantum dot molecules (QDMs) are one of the few quantum light sources that promise deterministic generation of one- and two-dimensional photonic graph states. The proposed protocol…
Coherent Dynamics of the Swing-Up Excitation Technique
Katarina Boos, Friedrich Sbresny, Sang Kyu Kim +9
Developing coherent excitation methods for quantum emitters which enable high brightness, good single-photon purity and high indistinguishability of the emitted photons has been a…
Quantum dot molecule devices with optical control of charge status and electronic control of coupling
Frederik Bopp, Jonathan Rojas, Natalia Revenga +13
Tunnel-coupled pairs of optically active quantum dots - quantum dot molecules (QDMs) - offer the possibility to combine excellent optical properties such as strong light-matter cou…
Stimulated generation of indistinguishable single photons from a quantum ladder system
Friedrich Sbresny, Lukas Hanschke, Eva Schöll +7
We propose a scheme for the generation of highly indistinguishable single photons using semiconductor quantum dots and demonstrate its performance and potential. The scheme is base…
The crux of using the cascaded emission of a 3-level quantum ladder system to generate indistinguishable photons
Eva Schöll, Lucas Schweickert, Lukas Hanschke +13
We investigate the degree of indistinguishability of cascaded photons emitted from a 3-level quantum ladder system; in our case the biexciton-exciton cascade of semiconductor quant…
