First-principle predictions of fragmentation functions via quantum computing
Researchers have proposed an algorithm that computes fragmentation functions directly from a light-front gauge formulation of the QCD Hamiltonian, intended for digital quantum computers. The approach is being validated through classical simulations of quantum computer behaviour, as reported in the abstract.

This could enable first-principle quantum computations of simplified fragmentation functions for selected hadrons within two years, providing cross-checks against classical lattice or Monte Carlo results.
The abstract's classical cluster simulations suggest the authors are already testing the algorithm at small scale; if qubit and gate-count requirements can be reduced to fit near-term error-mitigated devices, a limited but physically meaningful calculation may become feasible without waiting for full fault tolerance.
