Physicists observe entangled quarks for the first time

Scientists have observed entanglement in top-quark pairs for the first time by quantum feat. The entanglement was observed by observing entangled quarks, as per a press release. The physicists used the Tevatron’s high-energy particle accelerator to measure the Spin Quantum Numbers of Fundamental Fermions and Top Quarks. They found entangled quarks can be seen even without hadronisation.
