Quantum information as a guiding principle for fundamental interactions

Abstract: What if the symmetries of nature are not inputs but outputs, emergent consequences of quantum information theory? In 2017, we showed that demanding maximal entanglement in high-energy scattering processes reproduces the structure of QED and places non-trivial constraints on the weak mixing angle, hinting at a deep connection between quantum information and the laws of particle physics. Since then, this program has grown into a vibrant field: entanglement extremization is now linked to the emergence of symmetries across QCD, the Higgs sector, and flavor physics, while novel quantum resources such as magic-state complexity are revealing new organizing patterns behind the Standard Model. Strikingly, these are no longer purely theoretical constructs: ATLAS and CMS have observed quantum entanglement in top-quark pairs at the LHC, Bell inequality violations have been detected in charmonium and B meson decays, and quantum magic in top quarks has been measured for the first time, turning particle colliders into quantum information laboratories. In this talk, I will survey this landscape and outline a research vision that combines quantum information theory, high-energy phenomenology, and quantum computing to ask: can the fundamental interactions emerge from information-theoretic first principles?
