Quantum Effects in Gravity Waves

Understand

We discuss the quantum mechanical description of a gravitational wave interacting with a cavity electromagnetic field.

• Quantum fluctuations of the gravitational vacuum induce squeezing in the optical field.
• Moreover, this squeezing experiences revivals, a purely quantum effect.
• Measuring these gravitationally induced revivals, although out of reach from experiments, would provide evidence on the quantum nature of gravity.
