We show that when the gravitational field is treated quantum-mechanically, it induces fluctuations -- noise -- in the lengths of the arms of gravitational wave detectors. The characteristics of the noise depend on the quantum state of the gravitational field, and can be calculated exactly in several interesting cases. For coherent states the noise is very small, but it can be greatly enhanced in thermal and (especially) squeezed states. Detection of this fundamental noise would constitute direct evidence for the quantization of gravity and the existence of gravitons.

Suppressed Quantum Effects of Weakly Coupled Waves
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...

Graviton-induced which-path decoherence in matter-wave interferometry
Radiative graviton decoherence in matter-wave interferometers is shown to be far below detection, even with strongly squeezed inflationary graviton states.

Binary gravitational waves as probes of quantum graviton states
Gravitational waves from binaries can, in principle, carry sub-Poissonian graviton statistics inherited from a squeezed primordial vacuum, offering a new signature of quantum gravity.

(De)Coherence of a quantum system in an anti-de Sitter spacetime
An oscillator coupled to the confined graviton modes of AdS has an oscillatory decoherence rate; setting its revival period equal to the boundary light-crossing time yields the selection rule 2n+ℓ = 2(1+ω_m L/c) and p...

Observer Time from Causality in Perturbative Quantum Gravity
A lightbulb-and-mirror protocol defines diffeomorphism-invariant elapsed proper time, and its leading quantum gravity correction makes the time a noncommuting quantum operator.

Generalized Glauber theorem for dark-matter axion and graviton detection
The time-evolution operator for any Hamiltonian quadratic in creation and annihilation operators coupled to classical sources factorizes exactly into displacement, squeeze, and rotation operators, whose parameters obe...

Intermittency in Quantum Graviton-Phonon Conversion
Exact rotating-wave treatment of graviton-phonon conversion restores unitarity and predicts intermittent bursts for coherent states and suppression for squeezed states.

Toward graviton detection via photon-graviton quantum state conversion
Photon-to-graviton conversion in a magnetic field is shown to be enhanced by squeezed photon states and by the squeezed vacuum of primordial gravitational waves, with entanglement generation proposed as a quantum signature.

Cylindrical gravitational impulse wave
A two-soliton solution in Jordan-Ehlers spacetime is recast with the Piran et al. decomposition to produce explosion and implosion gravitational wave profiles, then tuned visually to mimic LIGO chirps.
