Physicists Observe Entangled Quarks for the First Time

Scientists at CERN have observed quantum entanglement between quarks for the first time, a significant breakthrough in understanding particle physics. The discovery, announced in a September 2024 study, involved analyzing top and anti-top quark pairs generated from proton collisions. This observation confirms predictions of entanglement at high energies and could enhance research on the role of quantum mechanics in particle behavior. The findings pave the way for further exploration of entanglement in other particles.
