  We motivate the use of quantum algorithms in particle physics and provide a
brief overview of the most recent applications at high-energy colliders. In
particular, we discuss in detail how a quantum approach reduces the complexity
of jet clustering algorithms, such as anti-kT , and show how quantum algorithms
efficiently identify causal configurations of multiloop Feynman diagrams. We
also present a quantum integration algorithm, called QFIAE, which is
successfully applied to the evaluation of one-loop Feynman integrals in a
quantum simulator or in a real quantum device.
