Due to Earth's rotation, two different paths corresponded to slightly different travel distances for each photon.
Experiment is the largest and most precise quantum-optical Sagnac interferometer to date, exhibiting sufficient sensitivity to detect Earth's rotation.
Quantum interference when they exited the labyrinth could be measured and translated into a rotation speed that agreed with Earth's known rate.
Two indistinguishable photons propagated inside the fiber interferometer, and their entanglement was created before being coupled in.

In a groundbreaking experiment, physicists from the University of Vienna have measured Earth's rotation rate using quantum entanglement in a large-scale interferometer. This marks the largest and most precise quantum-optical Sagnac interferometer to date, exhibiting sufficient sensitivity to detect Earth's rotation.
The team, led by Dr. Philip Walther, sent pairs of entangled photons through a 2-km long optical fiber that functioned as an interferometer with an effective area of over 700 m². The experiment was designed to test the effect of Earth's rotation on the entangled particles.
Two indistinguishable photons were propagated inside the fiber interferometer, and their entanglement was created before being coupled in. Due to Earth's rotation, two different paths corresponded to slightly different travel distances for each photon. This caused quantum interference when they exited the labyrinth, which could be measured and translated into a rotation speed that agreed with Earth's known rate.
The experiment represents a significant achievement in pushing the boundaries of rotation sensitivity in entanglement-based sensors, potentially setting the stage for further advancements. This technique could lead to more precise measurements of Earth's rotation and other rotating objects, as well as potential applications in gravitational wave detection and fundamental physics research.
Is the measurement of Earth's rotation rate using quantum entanglement a new discovery? (Answer: Yes, it is a significant achievement in pushing the boundaries of rotation sensitivity in entanglement-based sensors.)
A team of researchers led by Philip Walther at the University of Vienna conducted an experiment to measure the effect of Earth’s rotation on quantum entangled photons.
,
The experiment involved using a giant optical fiber Sagnac interferometer and keeping the noise low and stable for several hours to detect enough high-quality entangled photon pairs.
Two entangled photons behaved like a single particle testing both directions simultaneously while accumulating twice the time delay compared to non-entangled particles, a property known as super-resolution.

The article contains an appeal to authority when it states 'This confirms the interaction between rotating reference systems and quantum entanglement, as described in Einstein’s special theory of relativity and quantum mechanics.' This statement is not a logical fallacy on its own, but it can be considered an appeal to authority because the authors are citing Einstein's theories as evidence for their findings without providing any additional reasoning or evidence. However, since this is the only instance of an appeal to authority in the article and it does not significantly impact the overall argument or accuracy of the information presented, I am scoring it a 95.

No informal fallacies were found. There are some appeals to authority and a few instances of inflammatory rhetoric. The author quotes Dr. Philip Walther, Dr. Raffaele Silvestri, and Dr. Haocun Yu throughout the article as experts on the subject matter, which is an appeal to authority.
. . . with recent advances in technology, interferometers can nowadays also operate using various different quantum systems including electrons, neutrons, atoms, superfluids, and Bose-Einstein condensates.
The team's work appears in the journal Science Advances.
