Measuring Earth’s Rotation with Quantum Entanglement

A Quantum Leap in Measuring Earth’s Rotation

For over a century, scientists have used devices called interferometers to measure Earth’s rotation. Now, researchers at the University of Vienna have taken this a step further by using quantum entangled light particles, known as photons, to achieve the most precise measurement yet. Their groundbreaking experiment, published in Science Advances, showcases how quantum physics can enhance our understanding of...
