Einstein’s “spooky action” just survived one of physics’ most extreme tests
Physicists at CERN have successfully demonstrated quantum entanglement between Z bosons, which are massive, short-lived particles. This experiment confirms that quantum phenomena can persist even under the extreme high-energy conditions found in particle colliders.
Why it matters
This finding validates fundamental quantum mechanics theories at extreme energy scales, which is essential for the future development of quantum computing and secure communication technologies.
Physicists at the University of Oxford have helped demonstrate that one of quantum physics' strangest phenomena, quantum entanglement, can persist even among some of the heaviest and shortest-lived particles ever produced. The finding, made with CERN's powerful Large Hadron Collider, has been published in Physical Review Letters .
Quantum entanglement occurs when two particles share properties in such a way that measurements of one can reveal information about the other, even when the particles are separated. The connection is one of the most counterintuitive features of quantum mechanics and has challenged physicists' understanding of reality for decades.
