Researchers carried out a pioneering experiment where they measured the effect of the rotation of Earth on quantum entangled photons. The work represents a significant achievement that pushes the boundaries of rotation sensitivity in entanglement-based sensors, potentially setting the stage for further exploration at the intersection between quantum mechanics and general relativity.
Physicists at the University of Vienna have experimentally measured the rotation rate of our planet using maximally path-entangled quantum states of light in a large-scale interferometer.
