Using an atom interferometer to infer gravitational entanglement generation

Understand

If gravitational perturbations are quantized into gravitons in analogy with the electromagnetic field and photons, the resulting graviton interactions should lead to an entangling interaction between massive objects.

• We suggest a test of this prediction.
• To do this, we introduce the concept of interactive quantum information sensing.
• This novel sensing protocol is tailored to provable verification of weak dynamical entanglement generation between a pair of systems.
