Einstein's spooky action survives physics' most extreme test

So here's something really exciting - physicists at Oxford and CERN have just shown that quantum entanglement, that weird phenomenon Einstein called "spooky action at a distance," can actually survive in some of the heaviest and shortest-lived particles ever created. They studied Z bosons produced in the violent collisions at the Large Hadron Collider, particles that exist for just a fraction of a second before falling apart. By measuring the electrons and muons left behind, they could reconstruct the Z bosons' spins and confirm they showed the strange quantum correlations we'd expect from entanglement. This is huge because it shows that this fundamental quantum effect isn't delicate at all - it's robust enough to survive even in the most extreme conditions nature can throw at it, which gives us real confidence that the same rules powering tomorrow's quantum computers are woven into the fabric of reality itself.
