Efficient time-bin qubit analyzer compatible with multimode optical channels

2015 · arXiv (Cornell University)

Time-bin encoded photonic qubits are robust against decoherence in birefringent media such as optical fibers, which has led to many successful quantum communication demonstrations, including a Mach-Zehnder interferometer-based system, plug-and-play quantum key distribution (QKD), differential …

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 …
