Interferometric Quantum Polynomial Chaos Expansion as a Generative Model for Calorimeter Shower Simulation
Researchers propose an interferometric quantum algorithm that implements polynomial chaos expansion, framing it as a generative model for simulating calorimeter showers in particle physics. The method encodes uncertainty through quantum interference and could be executed on photonic quantum processors.

This could enable near-term photonic quantum processors to serve as efficient generative models for particle physics simulations, providing faster and more accurate data generation for experiments like those at CERN.
The approach leverages interferometric circuits, which are a natural fit for photonic quantum computers, and the polynomial chaos expansion is known to reduce computational complexity. If the quantum implementation offers polynomial speedup, it might be practical on small-scale devices within two years.
