Explore a groundbreaking laboratory scheme to test the nonclassical behavior of gravity through quantum technologies in this 17-minute conference talk. Learn about matter wave interferometry with large objects using the Stern-Gerlach interferometer as a foundational method. Discover how gravitational entanglement generation between two matter wave interferometers formed of large objects can be tested by measuring spins, and understand the theoretical justification for this approach in proving the quantum nature of gravity. Examine the principal practical challenges facing this experimental approach and explore potential mitigation methods to overcome these obstacles. Gain insights into cutting-edge table-top experimental physics that pushes beyond the current frontier of fundamental physics research, presented as part of the Simons Foundation's program supporting high-risk, potentially high-return small-scale experimental projects.
