Limits to the validity of gravitational redshift as a quantum-optical multimode mixer
Nils Leber, Luis Adrián Alanís Rodríguez, Alessandro Ferreri +2
We analyze the domain of validity of a quantum optical model that describes the effects of gravitational redshift on the quantum state of photons that propagate in curved spacetime…
