We report on a systematic study on the entanglement between helicity degrees of freedom generated at tree-level in quantum electrodynamics two-particle scattering processes. We determine the necessary and sufficient dynamical conditions for outgoing particles to be entangled with one another, and expose the hitherto unknown generation of maximal or nearly maximal entanglement through Bhabha and Compton scattering. Our work is an early step in revisiting quantum field theory and high-energy physics in the light of quantum information theory.

  1. Photon-nucleon entanglement in Compton scattering at low and high energies

    hep-ph 2026-08 conditional novelty 7.0 of 10

    Photon-nucleon entanglement in polarized Compton scattering is generically present and, for neutrons, strongly controlled by the nucleon electric and magnetic polarizabilities.

  2. Magic without a phase: phase-independent stabilizer R\'enyi entropy in gluon scattering

    hep-th 2026-07 conditional novelty 7.0 of 10

    A phase-averaged stabilizer Rényi entropy is introduced for tree-level gluon scattering, with color-independent phase-independent magic that is larger in 3→2 than 2→2 and has a soft-limit lower bound in 2→3.

  3. Spin versus Magic: Lessons from Gluon and Graviton Scattering

    hep-th 2025-08 accept novelty 6.0 of 10

    For 2 to 2 scattering of massless spin-1/2 to spin-2 particles, the averaged generated magic decreases monotonically with spin, with maxima well below the two-qubit upper bound.

  4. Testing spooky action between free-traveling electron-positron pairs

    hep-ph 2025-02 conditional novelty 5.0 of 10

    Simulations show that Bhabha scattering can produce electron-positron pairs with near-maximal entanglement, and a two-target secondary-scattering scheme could in principle measure their spin correlations.
