Physicists confirm that quantum entanglement persists between top quarks, the heaviest known fundamental particles

by

This article was reviewed according to Science fact checked trusted source proofread OK! Experimenting with entanglement: inside the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider. Rochester physicists working on the detector have observed that the spin entanglement between top quarks and top antiquarks persists at long distances and high speeds. Credit: Maximilien … Read more

Quantum entangled photons respond to the Earth’s rotation

by

The experiment was depicted by drawing a Sagnac interferometric fiber scheme 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 team of … Read more
