Abstract

Theoretical predictions for high-energy collision processes at particle colliders, such as the Large Hadron Collider (LHC), rely on calculations in perturbative Quantum Chromodynamics (QCD), which are often computationally challenging. In these conference proceedings, we explore the possibility of using quantum computers to simulate QCD processes in the perturbative QCD regime. In particular, as a first step towards that goal, we present quantum circuits to simulate the colour part of perturbative QCD. The circuits are validated by implementing them on a simulated quantum computer and verifying the colour factors for several example Feynman diagrams.
