@article{Wu2022HowGF, title={How gravitational fluctuations degrade the high-dimensional spatial entanglement}, author={Haorong Wu and Xilong Fan and Lixiang Chen}, journal={Physical Review D}, year={2022} }

Twisted photons carrying orbital angular momentum (OAM) are competent candidates for future interstellar communications. However, the gravitational ﬂuctuations are ubiquitous in spacetime. Thus a fundamental question arises naturally as to how the gravitational ﬂuctuations aﬀect the coherence and the degree of high-dimensional OAM entanglement when twisted photons travel across the textures of curved spacetime. Here, we consider the covariant scalar Helmholtz equations and the Minkowski metric…

### Gravitational Decoherence and the Possibility of Its Interferometric Detection.

A general master equation describing the quantum dynamics of a scalar bosonic field interacting with an external weak and stochastic gravitational field is presented, reproduces, thus generalizing, the previous results in the literature by taking appropriate limits.

The results show that classical dephasing processes arising from site level fluctuations lead to a monotonic decay of purity, and that the quantum mechanical decoherence events associated with spontaneous phonon emission are responsible for the subsequent recovery of purity.

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.…

The current race in quantum communication, endeavouring to establish a global quantum network, must account for special and general relativistic effects. For example, Shapiro time-delay,…

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…

We investigate the dynamics of two quantum mechanical oscillator system-bath toy models obtained by dimensionally truncating linearized gravity coupled to a massive scalar field and scalar QED. The…

- PhysicsScience

A quantum optical experimental test of event formalism of quantum fields, a theory that attempts to present a coherent description of Quantum fields in exotic spacetimes containing closed timelike curves and ordinary spacetime, reports results that are consistent with the standard quantum theory and hence do not support the prediction ofevent formalism.

We derive a general quantum master equation for the dynamics of a scalar bosonic particle interacting with a weak, stochastic and classical external gravitational field. The dynamics predicts…
