On Friday, October 16, a seminar will be held in Grandori Room (Campus Leonardo, Building 4, floor -1), starting at 15:00.

The seminar will be given by Michele Grossi, CERN Quantum Technology Initiative, and is titled “What Can Quantum Computers Do for High Energy Physics? Algorithms, Regimes and Computational Impact”.

Abstract
High energy physics pushes classical computing to its limits, from precision calculations in perturbation theory to strongly coupled, real-time problems that remain out of reach. Within its Quantum Technology Initiative, CERN is assessing how quantum technologies can address these long-term needs.

In this seminar I will discuss the role of quantum computing in HEP, from perturbative regimes (amplitude calculations, phase-space integration, sampling) to non-perturbative problems (real-time dynamics, lattice gauge theories) where classical methods face the sign problem and exponential Hilbert-space growth. After a brief introduction to the promise of quantum technologies, I will present the main classes of quantum algorithms relevant to these tasks, including Hamiltonian simulation and quantum machine learning, and assess their resource requirements and expected computational impact, near-term and fault-tolerant. I will conclude with open challenges and the research directions pursued by our group at CERN.

Speaker’s bio
Michele Grossi received his industrial PhD in High Energy Physics from the University of Pavia, working on quantum machine learning models for boson polarisation discrimination. He worked for several years as Quantum Technical Ambassador and Hybrid Cloud Solution Architect at IBM. In his current role at CERN he coordinates and supervises a group of researchers focusing on the application of quantum algorithms. His main research directions are quantum machine learning and the investigation of distributed quantum computing, together with the development of hybrid classic-quantum algorithm pipelines for theoretical and experimental physics and beyond.
