The ERC Synergy Grant GRAVITES will break new ground by studying experimentally how quantum entanglement is influenced by gravity. Quantum entanglement is a key, yet bizarre, feature of quantum physics that allows two or more particles to exhibit correlations stronger than classically allowed. When two particles are entangled a “spooky action at a distance” – as Einstein called it – can be observed: as soon as the quantum state of a particle is measured, the state of an entangled partner changes accordingly, regardless of how far apart the entangled particles might be.
