Researchers at the University of Vienna have successfully measured Earth's rotation impact on quantum entangled photons using a giant optical fiber Sagnac interferometer. The experiment, a thousand times more precise than previous ones, could lead to advancements in quantum mechanics and general relativity by investigating interactions between quantum entanglement and rotating reference systems.
