Monte Carlo integration is a fundamental method underpinning Monte Carlo simulations in high-energy physics (HEP). In this talk, I will present universal “building blocks” for quantum-enhanced integration of generic cross sections in HEP , based on Fourier Quantum Monte Carlo Integration. Leveraging Quantinuum’s Quantum Monte Carlo Integration engine, this approach enables the efficient generation of quantum circuits for these calculations, achieving a quadratic speed-up in root mean-squared error convergence compared to classical methods. To illustrate its impact, I will walk through a concrete example of a 1→3 decay process, demonstrating how quantum algorithms can enhance integral estimation in HEP and potentially reshape computational strategies in the future.
