Using the ATLAS detector's sophisticated tracking and calorimetry to reconstruct the decay of top quarks with extreme precision.
Observation of quantum entanglement with top quarks at the ATLAS detector Authors: ATLAS Collaboration Publication: Nature , Volume 633, pages 542–547 (2024). Core Findings EntanglementHD
Analysis was focused on a restricted phase space (close to the production threshold) where entanglement signals are strongest. EntanglementHD
It demonstrates quantum entanglement at an energy scale much higher (TeV range) than previously achieved in systems like photons or atoms. EntanglementHD
The researchers measured the spin correlations of top quark and antiquark pairs produced at the Large Hadron Collider (LHC).
This paper reports a landmark observation in particle physics:
