Recently, it has been proposed a new method [arXiv:2405.21029] to detect quantum gravity effects, based on generating gravitational entanglement between two nano-diamonds with Nitrogen-Vacancy defects, in a magnetically trapped configuration. Here we analyse in detail the proposed experimental setup, with a particular focus on implementing the detection of the gravitationally-induced entanglement using an optical readout based on measuring the position of the nano-diamonds and its complementary basis. We also summarise some of the key theoretical and experimental ideas on which this proposed scheme is based.

  1. Matter-Field Exchange Generates Entanglement, Not Classical Gravity

    quant-ph 2026-07 accept novelty 7.0

    The Aziz-Howl non-separable term is a matter-field exchange channel that vanishes for distinct non-interconverting species or with a barrier, not classical-gravity mediation of entanglement.

  2. Demonstration of quantum random number generation using nitrogen vacancy centres

    quant-ph 2026-04 conditional novelty 5.0

    QRNG using photon arrival times from NV centers in nanodiamonds achieves rates from 0.173 to 4.77 Mbits/s with min-entropy close to 1 and passes ENT/NIST tests without post-processing.

  3. Repulsive Gravitational Force as a Witness of the Quantum Nature of Gravity

    quant-ph 2026-02 conditional novelty 5.0

    A postselected quantum interference effect can make a probe mass move opposite to the gravitational pull, proposed as a witness of quantum gravity.
