The interpretation of measurements of high-energy particle collisions relies heavily on the performance of full event generators. By far the largest amount of time to predict the kinematics of multi-particle final states is dedicated to the calculation of the hard process and the subsequent parton shower step. With the continuous improvement of quantum devices, dedicated algorithms are needed to exploit the potential quantum computers can provide. In this talk I will discuss general and extendable algorithms for quantum gate computers to facilitate calculations of helicity amplitudes and the parton shower process, as a first step towards a quantum computing algorithm to describe the full collision event at the LHC. This method exploits the equivalence between spinors and qubits and harnesses the quantum computer’s ability to remain in a quantum state throughout the calculations.
