Photonic Cluster State Generation from a Quantum Dot Emitting in the Telecom C-band
Giora Peniakov, Reza Hekmati, Johannes Michl +9
Photonic cluster states are a key resource for photonic quantum information processing. So far, deterministic generation of these states has been limited to the near-infrared wavel…
Experimental observation of hyperbolic spacetime dynamics
Jonas Himmel, Coraline Bacq, Krishna Chand Maurya +11
Understanding quantum dynamics in curved spacetime is a central challenge at the intersection of quantum mechanics and gravity. Anti-de-Sitter (AdS) spacetime plays a pivotal role…
Gigahertz-clocked Generation of Highly Indistinguishable Photons at C-band Wavelengths
Robert Behrends, Lucas Rickert, Nils D. Kewitz +9
High-performance single-photon sources at telecom C-band wavelentghs are key building blocks for applications in long-distance quantum communication. Here, we report the generation…
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…
Electrically tunable orbital coupling and quantum light emission from O-band quantum dot molecules
P. S. Avdienko, L. Hanschke, Q. Buchinger +10
We present the observation of electrically tunable quantum coupling of orbital states in individual InAs/InGaAs quantum dot molecules emitting in the telecom O-band (~1300 nm). By…
Highly-Indistinguishable Single-Photons at 1550 nm from a Two-photon Resonantly Excited Purcell-enhanced Quantum Dot
Robert Behrends, Martin v. Helversen, Pratim K. Saha +10
In this work we present a cavity-enhanced InAs/ quantum dot (QD) single-photon source in the telecom C-band with a record-low biexciton emit…
