Physics inspired quantum algorithm for QCD splitting functions

Cenk T\"uys\"uz, Gabriel Rouxinol, Michele Grossi, Sofia Vallecorsa, Yacine Haddad

A two-qubit quantum circuit reproduces the helicity entanglement and momentum sharing of gluon splittings in QCD and composes into multi-prong distributions that match LHC jet data.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

For the pure-gluon channel, we derive an analytic expression for the helicity entanglement generated at the splitting vertex, quantified via the concurrence, and construct a two-qubit circuit whose measurement outcomes encode the momentum shared between outgoing gluons while reproducing the QCD-predicted entanglement structure.

C2weakest assumption

That the single-splitting entanglement structure and momentum mapping, once calibrated to data, can be directly composed across multiple independent splittings to produce accurate multi-prong distributions without additional interference terms or higher-order QCD corrections.

C3one line summary

A modular two-qubit quantum circuit is constructed to encode the concurrence of helicity entanglement in pure-gluon splitting, with parameters calibrated to LHC jet data so that composed circuits reproduce experimental multi-prong momentum fractions.
