Breaking the boundaries of classical physics: quantum entanglement measures the Earth’s rotation like never before

SciTechDaily

The experiment was depicted by drawing an interferometric scheme of Sagnac fibers in a magnifying inset, starting from a local position (Vienna, Austria) of the rotating Earth. Two indistinguishable photons impinge on a beam splitter cube, entanglement occurs between them and then they are coupled in the fiber interferometer. Credit: Marco Di Vita A quantum … Read more
