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…
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…
Assessing the alignment accuracy of state-of-the-art deterministic fabrication methods for single quantum dot devices
Abdulmalik A. Madigawa, Jan N. Donges, Benedek Gaál +13
The realization of efficient quantum light sources relies on the integration of self-assembled quantum dots (QDs) into photonic nanostructures with high spatial positioning accurac…
Controllable Spin-Resolved Photon Emission Enhanced by Slow-Light Mode in Photonic Crystal Waveguides on Chip
Shushu Shi, Shan Xiao, Jingnan Yang +17
We report the slow-light enhanced spin-resolved in-plane emission from a single quantum dot (QD) in a photonic crystal waveguide (PCW). The slow light dispersions in PCWs are desig…
Scalable deterministic integration of two quantum dots into an on-chip quantum circuit
Shulun Li, Yuhui Yang, Johannes Schall +9
Integrated quantum photonic circuits (IQPCs) with deterministically integrated quantum emitters are critical elements for scalable quantum information applications and have attract…
Tailoring solid-state single-photon sources with stimulated emissions
Yuming Wei, Shunfa Liu, Xueshi Li +12
The coherent interaction of electromagnetic fields with solid-state two-level systems can yield deterministic quantum light sources for photonic quantum technologies. To date, the…
Analysis of Emission Dynamics of a Long Lifetime in Single InAs/GaAs Quantum Dots
Junhui Huang, Hao Chen, Zhiyao Zhuo +8
A very long lifetime emission with non-single exponential decay characteristic has been reported for single InAs/GaAs quantum dot (QD) samples, in which there exists a long-lived m…
