Physicists measured Earth’s rotation using quantum entanglement! Since when has classical wave interference become “Quantum interference”?

The experimental setup as described in the original Silverstein et al 2024 experiment is fairly complex compared to the original Sagnac version. However complexity here does not mean it is no longer a basic time of flight Sagnac interferometer with observations consistent with a classical wave only model of light.
I’ve seen similar flights of fantasies of supposed ‘proof of QT’ from other very well known “Quantum” experiments. For instance the Kim et al 1999 Delayed Choice quantum eraser experiment. Where on analysis they had only confirmed the classical model of light. Where light is a wave only and not a photon.
The technique is also used here. QT ‘researchers’ also have made the experiment as complex as possible so as to disguise the fact that the experiment can still be explained classically without referring to relativity or QT. I have comprehensively dissected Kim et al’s Delayed choice experiment setup and shown how adding complexity is also used to prove Quantum fantasies, at this following link http://physicsexplained.blogspot.com/2015/11/the-main-illustrationbelow-is-schematic.html
The same applies to this current 2024 experiment. They manage to pull off this Quantum trick by pretending that somehow ...classical polarised states of wave only light and wave interference are signs of the light being a particle and subject to quantum nuttiness!!
The fact is that in this experiment there is still only just a path difference detected. And it is detected, as usual for any Sagnac interferometer, via interference patterns. Nothing more. They even admit this is all thats observed. The sleight of hand here is QT dogma at its greatest. They pretended that classical wave interference, observed and documented for centuries by Young and others... is somehow now called “Quantum Interference”
Laughable nonsense as usual from establishment physicists.
