Z-boson pairs at CERN reportedly show evidence of quantum entanglement

A post citing an ATLAS Collaboration paper says the non-entangled explanation was rejected at 4.7 standard deviations.

⚛️ CERN JUST FOUND QUANTUM ENTANGLEMENT IN HEAVY PARTICLES

Scientists at CERN’s ATLAS experiment found strong evidence that **two Z bosons produced from a Higgs boson can become quantum entangled**.

Even though Z bosons are massive and extremely short-lived, their quantum states appear to remain deeply connected. The non-entangled explanation was rejected at **4.7 standard deviations**.

This pushes quantum entanglement into a new territory — **the extreme energy world of the Large Hadron Collider.*
