Controlled integration of selected detectors and emitters in photonic integrated circuits

2019 · Optics Express

Integration of superconducting nanowire single-photon detectors and quantum sources with photonic waveguides is crucial for realizing advanced quantum integrated circuits. However, scalability is hindered by stringent requirements on high-performance detectors. Here we overcome the yield …

Enhancing secure key rates of satellite QKD using a quantum dot\n single-photon source

2020 · arXiv (Cornell University)

Global quantum secure communication can be achieved using quantum key\ndistribution (QKD) with orbiting satellites. Established techniques use\nattenuated lasers as weak coherent pulse (WCP) sources, with so-called\ndecoy-state protocols, to generate the required single-photon-level pulses.\nWhile such approaches …
