Experiments at the Interface of General Relativity and Quantum Mechanics

Explore cutting-edge experiments that bridge general relativity and quantum mechanics in this conference talk by Ron Folman. Discover how modern quantum-optics technology enables groundbreaking research at the intersection of physics' two fundamental pillars, potentially providing new insights toward the long-sought unification of these theories. Learn about three specific experiments: clock interferometry where a single clock in spatial superposition experiences different proper times due to gravitational red shift, quantum domain observations of Einstein's equivalence principle, and ambitious work with nano-diamonds that leaps ten orders of magnitude in mass beyond atomic experiments. Understand how these table-top scale experiments, supported by the Simons Foundation's high-risk, high-return research program, push the boundaries of fundamental physics by incorporating both passive and active mass considerations, including Earth's gravitational field effects. Gain insight into how technological advances in quantum optics laboratories are opening new experimental pathways that may finally resolve the decades-long theoretical challenge of quantum gravity unification.
