Quantum entanglement is a fascinating feature of quantum physics—the theory of the very small. If two particles are quantum-entangled, the state of one particle is tied to that of the other, no matter how far apart the particles are.

Experiments at the Large Hadron Collider have shown that top quarks, the heaviest of all elementary particles, can end up being entangled. Such quantum entanglement is happening at the highest possible energy we have ever measured,

At the Large Hadron Collider in Geneva, the world's largest particle accelerator, an experiment called ATLAS has just found entanglement in pairs of top quarks: the heaviest particles known to science. The results are described in a new paper from my colleagues and me in the ATLAS collaboration, published today in Nature.

By smashing protons together at blinding speeds, scientists have shown that pairs of quarks display the phenomenon of quantum entanglement. The result could lead to fresh insight about one of the forces holding nuclei together.

Quantum entanglement and its real-world applications. Quantum entanglement is not just a theoretical concept, but has practical applications as well. Today, devices are available

Entanglement has yet to be studied much at the high energies of particle colliders like the Large Hadron Collider (LHC). In a new study, the ATLAS collaboration successfully observed quantum entanglement at the LHC for the first time. They observed quantum entanglement between top quarks and at the highest energies yet.

Entanglement, a surprising physics prediction, links distant objects as though they are connected. Traditionally

Quantum entanglement between a top quark and its antimatter counterpart was observed by the ATLAS and CMS teams at CERN.
