Theory Seminar

Quantum Algorithms for Particle Physics

by Lena Funcke (Uni Bonn)


In this seminar, I will present recent advances towards applying quantum computing to particle physics. Quantum technology offers the prospect to efficiently simulate sign-problem afflicted regimes in lattice field theory, such as the presence of topological terms, chemical potentials, and out-of-equilibrium dynamics. Moreover, quantum computing can be applied to quadratic unconstrained binary optimization problems in collider physics. The path towards quantum computing for (3+1)D particle physics requires many incremental steps, including algorithmic development, hardware improvement, methods for circuit design, as well as error mitigation and correction techniques. I will review these requirements, present new avenues to tackle some of these challenges, and discuss the main bottlenecks and future directions.
