Towards Stirling cooler operable single-photon sources based on low-noise GaAs quantum dots
Maximilian Aigner, Jana Schlücking, Eva Schöll +15
For photonic quantum technology applications, sources capable of emitting photons with indistinguishability close to unity are essential. Ideally, these sources should not require…
Coherent Control of Quantum-Dot Spins with Cyclic Optical Transitions
Zhe Xian Koong, Urs Haeusler, Jan M. Kaspari +14
Solid-state spins are promising as interfaces from stationary qubits to single photons for quantum communication technologies. Semiconductor quantum dots have excellent optical coh…
Optical and magnetic response by design in GaAs quantum dots
Christian Schimpf, Ailton J. Garcia, Zhe X. Koong +24
Quantum networking technologies use spin qubits and their interface to single photons as core components of a network node. This necessitates the ability to co-design the magnetic-…
Passive Demultiplexed Two-photon State Generation from a Quantum Dot
Yusuf Karli, Iker Avila Arenas, Christian Schimpf +11
High-purity multi-photon states are essential for photonic quantum computing. Among existing platforms, semiconductor quantum dots offer a promising route to scalable and determini…
Robust Single-Photon Generation for Quantum Information Enabled by Stimulated Adiabatic Rapid Passage
