Purcell enhanced and blinking free single photons from InAs/GaAs quantum dots in deterministically placed circular Bragg gratings
Peter Gschwandtner, Quirin Buchinger, Krishna Chand Maurya +11
The paper demonstrates a bright, charge‑tunable, blinking‑free single‑photon source based on InAs quantum dots embedded in a p‑i‑n GaAs membrane and coupled to a modified circular…
A diode nanocavity for fast, efficient and tunable emission of highly entangled photon pairs and Fourier-transform-limited single photons
Ievgen Brytavskyi, Thomas Oberleitner, Christian Weidinger +16
The paper presents a tunable p‑i‑n diode nanocavity that embeds a semiconductor quantum dot, achieving high extraction efficiency, strong Purcell enhancement, and low charge noise…
Molecular beam epitaxy of wafer-scale O-band InAs/InGaAs quantum dots on GaAs for quantum photonics
Pavel S. Avdienko, Lukas Hanschke, Quirin Buchinger +13
We report a scalable molecular beam epitaxy strategy to achieve a low density of O-band electrically tunable InAs/InGaAs quantum dots (QDs) on GaAs(001) substrates. Our approach is…
Cascaded Metasurface Interferometer for Multipath Interference with Classical and Quantum Light
Rebecca Aschwanden, Nicolás Claro-RodrÃguez, Ruizhe Zhao +14
Beamsplitters represent fundamental components in both classical and quantum optical systems, enabling the distribution of light, as well as the generation of interference, superpo…
Ability of entanglement and purity to help to detect systematic experimental errors
Julia Freund, Francesco Basso Basset, Tobias M. Krieger +12
Measurements are central in all quantitative sciences, and a fundamental challenge is to make observations without systematic measurement errors. This holds in particular for quant…
A Spin-Photon Interface in the Telecom C-Band with Long Hole Spin Dephasing Time
Johannes M. Michl, Reza Hekmati, Mohamed Helal +9
Matter qubits that maintain coherence over extended timescales are essential for many pursued applications in quantum communication and quantum computing. Significant progress has…
