• Authors: Alessandro Pesci, Pierbiagio Pieri
• Abstract summary: A setup is proposed that is based on a single delocalized mass coupled to a harmonically trapped test mass. We investigate the in-principle feasibility of such an experiment, which turns out to crucially depend on the ability to tame Casimir-Polder forces.

• Abstract: Most of the existing proposals for laboratory tests of a quantum nature of gravity are based on the use of two delocalized masses or harmonically bound masses prepared in pure quantum states with large enough spatial extent. Here a setup is proposed that is based on a single delocalized mass coupled to a harmonically trapped test mass (undergoing first expansion and then compression) that moves under the action of gravity. We investigate the in-principle feasibility of such an experiment, which turns out to crucially depend on the ability to tame Casimir-Polder forces. We thus proceed with a design aimed at achieving this, trying at the same time to take advantage of these forces rather than only fighting them.

  A novel detector concept exploits the dynamics of quantum phononic excitations in a trapped Bose-Einstein condensate (BEC) The BEC exhibits sensitivity unique to the two key components of the gravitational potential in $Lambda$-gravity. This experiment could establish the best Earth-based upper limit on $Lambda$ at $10-31$ m$-2$, marking the first laboratory-based probe of the cosmological constant.

  Experimental proposals for testing quantum gravity-induced entanglement of masses (QGEM) typically involve two interacting masses which are each in a spatial superposition state. Here, we propose a QGEM experiment with two particles which are each in a superposition of rotational states, this amounts to a superposition of mass through mass-energy equivalence.

We find that discriminating between the theories will be very difficult until experimental control over low frequency quantum optomechanical systems is pushed further.

• Gravity-induced entanglement as a probe of spacetime curvature [0.0]
  It is now widely believed that if the gravitational field is (perturbatively) quantum, it would entangle two massive objects. In this essay, we prove that such gravity-induced entanglement depends on the spacetime curvature and can, in principle, act as an alternate signature of the expanding background. This will open up new and complementary directions to search for such entanglement in curved spacetime and reveal fresh perspectives on it.

• Emerging (2+1)D massive graviton in graphene-like systems [0.0]
  Quantum aspects of gravity, such as massive gravitons, can emerge in experiments with fractional quantum Hall liquids. We employ (2+1)-dimensional Dirac fermions, emerging in the continuous limit of a fermionic honeycomb lattice, coupled to massive gravitons, simulated by bosonic modes. The similarity of our approach to current optical lattice configurations suggests that quantum signatures of gravity can be simulated in the laboratory in the near future.
