Cryogenic on-chip Levitated Optomechanics for a Spin Entanglement witness to Quantum Gravity
This proposal addresses one of the key challenges of modern physics: understanding the interface between quantum mechanics and general relativity. Recently, an experimental test was proposed that can directly witness the need to unify the two theories: observing quantum entanglement between objects that only interact through the gravitational field. A successful test would prove the existence of superpositions of space-time and have far-reaching implications on how we understand our world. So far, no experimental platform exists that can meet the challenging central requirement for this test: A picogram-scale mass in a micrometre-scale spatial superposition with a second-scale coherence…
