Single-Photon Advantage in Quantum Cryptography Beyond QKD
Daniel A. Vajner, Koray Kaymazlar, Fenja Drauschke +8
Quantum key distribution (QKD) can be used to establish a secret key between trusted parties. Many practical use-cases in communication networks, however, involve parties who do no…
A Fiber-pigtailed Quantum Dot Device Generating Indistinguishable Photons at GHz Clock-rates
Lucas Rickert, Kinga Żołnacz, Daniel A. Vajner +11
Solid-state quantum light sources based on semiconductor quantum dots (QDs) are increasingly employed in photonic quantum information applications. Especially when moving towards r…
High Purcell-enhancement in quantum-dot hybrid circular Bragg grating cavities for GHz-clockrate generation of indistinguishable photons
Lucas Rickert, Daniel A. Vajner, Martin von Helversen +8
We present Purcell-enhanced () semiconductor InAs quantum dot decay times of ps, enabled by deterministic hybrid circular Bragg gratings (hCBGs). We inve…
Convert laser light into single photons via interference
Yanfeng Li, Manman Wang, Guoqi Huang +11
Laser light possesses perfect coherence, but cannot be attenuated to single photons via linear optics. An elegant route to convert laser light into single photons is based on photo…
