Abstract: We analyze the domain of validity of a quantum optical model describing the effects of gravitational redshift on the quantum state of photons that propagate in curved spacetime. We find that the model is consistent for small redshift, but fails for larger redshifts. Surprisingly, the range of the redshift for which the model applies is conditional not only to the gravitational parameters, but also to those that define the photonic modes. We provide an analysis to characterize this aspect and propose a solution. Finally, we discuss implications for theoretical science as well as for the development of quantum technologies.

Gravitational redshift via quantized linear gravity [44.99833362998488]
We employ linearized quantum gravity to show that gravitational redshift occurs as a purely quantum process. Redshift occurs as predicted by general relativity but arises in flat spacetime in the absence of curvature. Results can help improve our understanding of the quantum nature of gravity in the low energy and low curvature regime.

Nonlinear dynamical Casimir effect and Unruh entanglement in waveguide QED with parametrically modulated coupling [83.88591755871734]
We study theoretically an array of two-level qubits moving relative to a one-dimensional waveguide. When the frequency of this motion approaches twice the qubit resonance frequency, it induces parametric generation of photons and excitation of the qubits. We develop a comprehensive general theoretical framework that incorporates both perturbative diagrammatic techniques and a rigorous master-equation approach.

Photon-Gravity Coupling in Schwarzschild Spacetime [0.0]
A canonical formalism for quantum electrodynamics in curved spacetime is developed. The claim that "the gravitational redshift is a shift in the sharp frequencies of the photons for all of the spectrum" is proved. It is shown the gravitational decoherence is due to photon-gravity coupling and observer-dependent quantum electrodynamics in curved spacetime phenomena.

Quantum interferences and gates with emitter-based coherent photon sources [0.0]
In 2019, it was shown that the emitted single photon states often include coherence with the vacuum component. We show how such photon-number coherence alters quantum interference experiments. We illustrate the impact on quantum protocols by evidencing modifications in heralding efficiency and fidelity of two-qubit gates.

Signatures of Quantum Gravity in the Gravitational Self-Interaction of Photons [0.0]
We propose relativistic tests of quantum gravity using the gravitational self-interaction of photons in a cavity. We demonstrate that this interaction results in a number of quantum gravitational signatures in the quantum state of the light that cannot be reproduced by any classical theory of gravity.

Photon-mediated Stroboscopic Quantum Simulation of a $\mathbb{Z}_{2}$ Lattice Gauge Theory [58.720142291102135]
Quantum simulation of lattice gauge theories (LGTs) aims at tackling non-perturbative particle and condensed matter physics. One of the current challenges is to go beyond 1+1 dimensions, where four-body (plaquette) interactions, not contained naturally in quantum simulating devices, appear. We show how to prepare the ground state and measure Wilson loops using state-of-the-art techniques in atomic physics.

Quantum Hall phase emerging in an array of atoms interacting with photons [101.18253437732933]
Topological quantum phases underpin many concepts of modern physics. Here, we reveal that the quantum Hall phase with topological edge states, spectral Landau levels and Hofstadter butterfly can emerge in a simple quantum system. Such systems, arrays of two-level atoms (qubits) coupled to light being described by the classical Dicke model, have recently been realized in experiments with cold atoms and superconducting qubits.
