Photonic Implementation of Quantum Gravity Simulator

7 Luglio 20227 Luglio 2022

On arxiv today the preprint of the work developed in the context of the international collaboration Quantum Information Structure of Spacetime (QISS). Detecting gravity mediated entanglement can provide evidence that the gravitational field obeys quantum mechanics. We report the result of a simulation of the phenomenon using a photonic platform. The simulation tests the idea … Continua a leggere

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

7 Luglio 20224 Luglio 2022

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. … Continua a leggere
