摘　　要：Application of quantum technologies to fundamental sciences has the potential to advance both fields simultaneously.In the near future,the number of reliable quantum operations in a real-world quantum computer will be constrained by noise and decoherence[1].To overcome these challenges,hybrid quantum-classical algorithms[2]have been proposed.A notable example is the quantum approximate optimization algorithm(QAOA)[3],an algorithm commonly used to address classical combinatorial optimization problems.In high-energy particle collisions,quarks and gluons are produced and immediately form collimated particle sprays,referred to as jets,due to color confinement[4].Accurate jet clustering is crucial to reconstruct the quark or gluon information and enhances the study of the properties of the Higgs boson.For the first time,we apply QAOA to the problem of jet clustering,as shown in Fig.1e,by mapping collision events into graphs,as shown in Fig.1d.We obtain experimental results on quantum computer simulators and quantum computer hardware and find that their performance is comparable to or even better than classical algorithms for a small-sized problem.
