Quantum memories for fundamental physics in space

Abstract

Investigations into the foundations of quantum mechanics and their link to gravity and general relativity require sensitive quantum experiments. To provide ultimate insight, the realization of such experiments in space will sooner or later become a necessity. With their advanced state and backed by decades of development, quantum technologies and among them quantum memories are providing novel approaches to reach conclusive experimental results. We therefore want to highlight the use case of quantum memories for investigations of fundamental physics in space, and discuss both concrete experiments as well as platforms and performance of candidate quantum memories.
