Quantum light sees quantum sound: phonon/photon correlations

> Ben Humphries, Ph.D. student in theoretical chemistry, at UEA said, "Our research shows that when a molecule exchanges phonons—quantum-mechanical particles of sound—with its environment, this produces a recognizable signal in the photon correlations."
> While photons are routinely created and measured in laboratories all over the world, individual quanta of vibrations, which are the corresponding particles of sound, phonons, cannot in general be similarly measured.
This is also the goal with phononic quantum computation iiuc
> The new findings provide a toolbox for investigating the world of quantum sound in molecules."
> Lead researcher Dr. Garth Jones, from UEA's School of Chemistry, said, "We have also computed correlations between photon and phonons.
> "It would be very exciting if our paper could inspire the development of new experimental techniques to detect individual phonons directly," he added.

Acoustic waves (phonons) affect electromagnetic waves (EM waves), which are also described as quantized quanta of light (photons)

Because the medium is fluidic, at least, I believe fluids are probably necessary to predict real-world phononic transmission with high accuracy; why does e.g. shortwave radio wave in and out given Earth's fluidic atmosphere?
