Overview

Theoretical proposal demonstrates direct observation of quantum gravity via entangled macroscopic masses, suggesting tabletop experimental verification of quantum gravitational effects.

Key Points

To establish a theoretical and mathematical framework for observing quantum gravity via tabletop entanglement experiments with macroscopic masses in spatial superposition.
Modeled the gravitational interaction Hamiltonian for two masses in coherent position superpositions.
Used entanglement entropy of the joint quantum state as a witness to verify non-classical gravitational interactions.
Calculated phase shift and decoherence rate scalings using a triple-interferometer configuration over interaction time T and separation distance d.
Demonstrated that the interferometer phase shift scales as Δϕ ∝ G m² T³ / (ℏ d²).
Identified that the environmental decoherence rate scales as Γ ∝ (G m² / ℏ d²)² τ across interaction time τ.
Showed that observable gravitational entanglement depends directly on the dimensionless coupling parameter G m² / ℏ.
