• Abstract: Models of gravitational decoherence are not commonly applied to ultra-relativistic systems, including photons. As a result, few quantum optical tests of gravitational decoherence have been developed. In this paper, we generalize the gravitational decoherence model of Anastopoulos and Hu (arXiv:1305.5231) to photons. In this model, decoherence originates from a bath of stochastic gravitational perturbations, possibly of fundamental origin. We derive a master equation for general states of the electromagnetic (EM) field; the only free parameter is a noise temperature $\Theta$ of the gravitational fluctuations. We find that interference experiments with long baselines, accessible in near-future experiments, can, in principle, lead to strong constraints in $\Theta$.

• Decoherence-Free Entropic Gravity for Dirac Fermion [0.0]
  One of the main criticisms of entropic gravity is that it would lead to quantum massive particles losing coherence in free fall. A nonrelativistic master equation modeling gravity as an open quantum system interaction demonstrated that in the strong coupling limit, coherence could be maintained. Motivated by this, we extend these results to gravitationally accelerating Dirac fermions.

  Einstein Equivalence Principle (EEP) underpins all metric theories of gravity. The iconic gravitational red-shift experiment places two fermionic systems, used as clocks, in different gravitational potentials. A fundamental point in the implementation of a satellite large-distance optical interferometric experiment is the suppression of the first-order Doppler effect. We propose a novel scheme to suppress it, by subtracting the phase-shifts measured in the one-way and in the two-way configuration between a ground station and a satellite.
