We show that gravitational-wave astronomy has the potential to inform us on quantum aspects of black holes. Based on Bekenstein's quantization, we find that black hole area discretization could impart observable imprints to the gravitational-wave signal from a pair of merging black holes, affecting their absorption properties during inspiral and their late-time relaxation after merger. In contrast with previous results, we find that black hole rotation, ubiquitous in astrophysics, improves our ability to probe quantum effects. Our analysis shows that gravitational-wave echoes and suppressed tidal heating are signs of new physics from which the fundamental quantum of black hole area can be measured, and which are within reach of future detectors. Our results also highlight the need to derive predictions from specific quantum gravity proposals.

  1. Covariant diffusion and drift of the stochastic GW background with LISA

    gr-qc 2025-05 conditional novelty 7.0 of 10

    A Fisher forecast shows LISA could bound graviton diffusion/drift parameters κ1, κ2 down to about 10^-56 kg m^2 s^-3, improving CMB bounds by 12 orders of magnitude, if a phase-transition or PBH background is detected.

  2. Hawking area law in quantum gravity

    gr-qc 2026-04 unverdicted novelty 5.0 of 10

    If Hawking's area law is taken as exact, nonlocal and Stelle quantum-gravity theories are forced to drop R^2 and (Riemann)^2 terms (or use singular Ricci-flat black holes), and the standard entropy-area law follows as...

  3. Probing the existence of a minimal length through compact binary inspiral

    gr-qc 2025-05 conditional novelty 5.0 of 10

    A minimum length in spacetime would make black holes perfectly reflective below a cutoff frequency, imprinting the inspiral waveform via modified tidal heating.

  4. Complementarity of Gravitational Collapse (I) Origin of the Bekenstein-Hawking Entropy

    gr-qc 2025-05 reject novelty 4.0 of 10

    The paper claims black hole entropy arises from counting quantum states of collapsing dust shells, with Schwarzschild and Lemaitre coordinates giving complementary views of the same horizonless interior.
