Anisotropic nanoscale coherent polariton transport in CrSBr
Paritosh Malik, Dogyun Ko, Vita Solovyeva +11
In a combined experimental and theoretical study, we demonstrate anisotropic polariton transport on the nanoscale in the van der Waals antiferromagnet CrSBr. While effective cavity…
Effective long-range attraction of moiré excitons under the influence of atomic reconstructions and anisotropic screening
Nils-Erik Schütte, Carl Emil Mørch Nielsen, Niclas Götting +3
The moiré pattern, which emerges due to a relative rotation between two monolayers of transition metal dichalcogenides, features a long lattice period for small twist angles. The r…
Scalable Quantum Photonic Platform Based on Site-Controlled Quantum Dots Coupled to Circular Bragg Grating Resonators
Kartik Gaur, Avijit Barua, Sarthak Tripathi +12
The scalable integration of solid-state quantum emitters into photonic nanostructures remains a central challenge for quantum photonic technologies. Here, we demonstrate a robust a…
Tunable WS Micro-Dome Open Cavity Single Photon Source
Jens-Christian Drawer, Salvatore Cianci, Vita Solovyeva +13
Versatile, tunable, and potentially scalable single-photon sources are a key asset in emergent photonic quantum technologies. In this work, a single-photon source based on WS m…
Rabi oscillations of a monolayer quantum emitter driven through its excited state
Victor N. Mitryakhin, Ivan A. Solovev, Alexander Steinhoff +5
The interaction of a quantum two-level system with a resonant driving field results in the emergence of Rabi oscillations, which are the hallmark of a controlled manipulation of a…
Enhancement of Indistinguishable Photon Emission from a GaAs Quantum Dot via Charge Noise Suppression
Priyabrata Mudi, Avijit Barua, Kartik Gaur +10
The generation of indistinguishable single photons is a fundamental requirement for future quantum technologies, particularly in quantum repeater networks and for distributed quant…
Electronic localization and optical activity of strain-engineered transition-metal dichalcogenide nanobubbles
Stefan Velja, Alexander Steinhoff, Jannis Krumland +2
Strain-engineered transition-metal dichalcogenide nanobubbles are promising platforms for quantum emission, as revealed by recent experimental observations. In this work, we presen…
Connection between memory performance and optical absorption in quantum reservoir computing
Niclas Götting, Steffen Wilksen, Alexander Steinhoff +2
The fading memory property is a key requirement for reservoir computers -- a specific type of recurrent neural network with fixed internal weights. While mostly undesired in gate-b…
Impact of phonon lifetimes on the single-photon indistinguishability in quantum emitters based on 2D materials
Alexander Steinhoff, Steffen Wilksen, Ivan Solovev +2
Localized excitons in two-dimensional (2D) materials are considered as promising sources of single photons on demand. The photon indistinguishability as key figure of merit for qua…
