Experimental quantum cryptography with single photons and imperfect devices
Aodhán Corrigan, Koray Kaymazlar, Zhiyao Wang +9
Quantum key distribution (QKD) allows for provably secure key distribution between two trusted parties. Because the security and performance of QKD protocols rely on devices that b…
Engineering energy-time entanglement from resonance fluorescence
Jian Wang, Xiu-Bin Liu, Ziqi Zeng +8
Resonance fluorescence from a coherently driven two-level emitter is a minimal quantum optical field that combines phase coherence with single-photon-level nonlinearity. Here we sh…
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 Å»oÅnacz, 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…
Bell Inequality Violation with Vacuum-One-Photon Number Superposition States
Zi-Qi Zeng, Jian Wang, Xiu-Bin Liu +8
Entanglement is a central resource in quantum technologies, and the realization of photonic entanglement necessarily relies on interaction with matter. Resonance fluorescence (RF),…
