Physicists confirm quantum entanglement in Z bosons at LHC
CERN scientists detect entanglement in heavy, short-lived particles created in 13-trillion-electron-volt collisions.
What to know
- CERN researchers detected quantum entanglement in Z bosons—extremely short-lived particles produced in 13-trillion-electron-volt collisions—marking one of the highest-energy confirmations of entanglement ever recorded.
- The discovery shows entanglement persists under the most extreme physical conditions, contradicting assumptions that the phenomenon is fragile and confined to laboratory settings.
- The finding has implications for developing quantum computers, next-generation sensors, and ultra-secure communication networks by revealing entanglement is a fundamental, robust feature of nature.
Entanglement's survival in extreme conditions reveals it is fundamental to nature rather than a delicate laboratory oddity.

International team confirms entanglement in Z bosons at CERN
Physicists using the ATLAS experiment at the Large Hadron Collider detected quantum entanglement in pairs of Z bosons created in proton collisions at 99.99% the speed of light, generating 13 trillion electron volts. The discovery, published in Physical Review Letters, is among the highest-energy confirmations of quantum entanglement ever recorded.
“Finding it alive and well among particles as heavy and short-lived as Z bosons, created in some of the most violent collisions we can produce on Earth, shows just how fundamental and robust this quantum effect really is.”

Entanglement survives a 13 trillion electron volt collision and turns up in Z bosons that exist for a sliver of a second. The spooky part was never really the distance. It is that the rule holds up in the most violent conditions human beings know how to build. Scientists make 'spooky' disco...
