QC4HEP Working Group Annual Meeting

Friday 24 Jan 2025, 09:00 → 18:00 Europe/Zurich

Ivano Tavernelli (IBM Research - Zurich), Michele Grossi (CERN), Sofia Vallecorsa (CERN), Voica Radescu

Welcome to the 2025 Working Group on Quantum Computing for HEP workshop! 

This technical working group organised by CERN, DESY, and the IBM Quantum Network aims to bring together experts to collaborate with a goal of accelerating our path to achieving quantum advantage for High Energy Physics (HEP).

11:00 → 11:15 Coffee break

11:15 → 12:30 Challenges: round table with a moderator - Topic: what are the challenges and how to overcome them in the next years

Theory: Karl J. & Martin S, & Jad A. & Alessandro R.;
Experiments: Sofia V., Michele G., Andrea D.)

12:30 → 14:00 Lunch

14:00 → 16:30 Parallel sessions: Experiments

Some potential topics for discussion:
o Parallelization of quantum classical workflow (chairperson: Andrea D.)
o (Large) data encoding and compression schemes (such as PCA) that can keep quantum correlation (chairperson: Miriam)
o Quantum Monte Carlo generators (chairperson: Vincent P.)
o QAOA (chairperson: Andrea)
o QML ((chairperson: Koji)
o Quantum generative models (can we make use of quantum data) (chairperson: Vincent C.)
o Role of quantum sensing (chairperson: Yacine)
Possible new research directions (all). Consolidate and/or start working teams working around selected topics.

14:00 → 16:30 Parallel sessions: Theory

Potential topics to discuss:

o Optimization: static calculations (phase transition) (chairperson: Name)
Topic: Beyond VQE(?); Martin’s “scaling” ansatz; Quantum subspace expansion (Laurin, Julian)
o Dynamics (chairperson: Stefan K. and Jad H.)
Topic: Scattering: how large can we scale? Can we reach utility scale?
o What else than Trotter? QDRIFT inspired ansatz, (chairperson: Alessandro R.).
o Scaling from 1D+1 to 2D+1 and possibly 3D+1 (HW dependences) – near-term vs fault-tolerant (what kind of chip topology will be needed?) (chairperson: Uwe W. and Karl J. and Arianna C.)
o Possible new research directions (all). Consolidate and/or start working teams working around selected topics.

16:30 → 17:00 Coffee break

17:00 → 18:00 General assembly (all together)

• Organization: future virtual and in-person meetings (chairperson: SteerCo)
• Identify needs (enablement required, …)
• Conduct guidelines (enrolment process, publication policy …) (chairperson: Ivano)
• Summary of the discussions and outlook (chairperson: SteerCo)
