We propose simple quantitative criteria, based on counting statistics in resonant harmonic detectors, that probe the quantum mechanical character of radiation fields. They provide, in particular, practical means to test the null hypothesis that a given field is ``maximally classical'', i.e., accurately described by a coherent state. We suggest circumstances in which that hypothesis plausibly fails, notably including gravitational radiation involving non-linear or stochastic sourcing.

  1. Suppressed Quantum Effects of Weakly Coupled Waves

    hep-ph 2026-07 conditional novelty 7.0 of 10

    Nonclassical (quantum) signatures of weakly coupled waves are suppressed by an extra power of the tiny conversion efficiency η (~10^-21 for axions, ~10^-33 for gravitons), so experiments cannot establish the quantizat...

  2. The Gravito-Phononic Effect: A Quantum Signature of Linearised Gravity

    quant-ph 2024-11 conditional novelty 3.0 of 10

    A coupled-oscillator model reproduces photoelectric signatures and is used to argue that discrete resonant energy transfer from gravitational waves to acoustic detectors would signal graviton quantization.
