Daylight entanglement-based quantum key distribution with a quantum dot source

Daylight entanglement-based quantum key distribution with a quantum dot source Abstract Entanglement-based quantum key distribution can enable secure communication in trusted node-free networks and over long distances. Although implementations exist both in fiber and in free space, the latter approach is often considered challenging due to environmental factors. Here, we implement a quantum communication protocol during daytime for the first time using a quantum dot source. This technology pres...
