Testing the quantumness of gravity without entanglement

Paris, France (SPX) May 02, 2024

Gravity, a fundamental force in our everyday lives, continues to puzzle scientists: Is it a geometric force as Einstein suggested, or does it follow quantum mechanics? Researchers from the University of Amsterdam and Ulm have introduced an innovative experiment to explore this, avoiding the challenges of previous methods that required entangling massive objects, which often lose their quantum pr
