Germán Rodrigo

Germán Rodrigo is a tenured Research Professor at the Instituto de Física Corpuscular (IFIC), a joint centre of the Spanish National Research Council (CSIC) and the University of Valencia. After earning his PhD in 2003 under Arcadi Santamaria, he held post-doctoral positions at KIT Karlsruhe and CERN before returning to Valencia in 2008. He currently leads the quantum–phenomenology group within the theoretical physics department.

His research straddles high-energy collider phenomenology and quantum computing. Rodrigo is internationally recognised for turning multi-loop Feynman integrals into causal, loop-tree-dual forms and for implementing the resulting algorithms on real quantum hardware. Key achievements include the first quantum calculation of loop integrals, quantum jet clustering at the LHC, and quantum amplitude estimation with error mitigation.

Recent work (2022-2025) focuses on:

• Quantum integration of decay rates and fragmentation functions
• Graph-based quantum algorithms for causal multi-loop configurations
• Adaptive importance sampling on quantum annealers and gate-based devices
• Factorisation-breaking studies in triple-collinear splitting with massive partons

He advises three doctoral students and is PI on a national Spanish grant supporting the group’s quantum-technologies programme. No personal e-mail is publicly listed; contact is handled through the IFIC secretariat.
