Overview

Theoretical analysis reveals constraints on Planck-scale collapse models in tabletop quantum systems, highlighting tighter bounds on gravitationally induced quantum decoherence.

Key Points

  • Assess how tabletop quantum experiments constrain Planck-scale discreteness, gravitationally induced collapse models, and graviton signatures.
  • Evaluated matter-wave interferometry and optomechanical superposition frameworks designed to probe physics near the Planck length and mass.
  • Calculated Penrose–Diósi gravitationally induced decoherence rates and cubic phase-shift scaling from quantum equivalence principle free-fall tests.
  • Established bounds that constrain wave-function collapse models and graviton signatures without requiring a fully resolved quantum gravity equation.
  • Identified that the ratio of squared Planck length to squared Compton wavelength directly influences gravitationally induced entanglement rates.
