Title: Quantum sources of gravity: the next frontier of macrosopic quantum physics
Abstract:
No experiment today provides evidence that gravity requires a quantum description. The
growing ability to achieve quantum optical control over massive solid-state objects may change
that situation -- by enabling experiments that directly probe the phenomenology of quantum
states of gravitational source masses. This can lead to experimental outcomes that are
inconsistent with the predictions of a purely classical field theory of gravity. Such 'Quantum
Cavendish' experiments will rely on delocalized motional quantum states of su...
