I am a PhD candidate at the Universitat Politècnica de Catalunya (UPC) and the Barcelona Supercomputing Center (BSC), where I am part of the Accelerators and Communications for HPC (AccelCom) group. My research focuses on the integration of quantum processors into high-performance computing: how to schedule, distribute and orchestrate quantum workloads alongside classical resources in a supercomputing centre.

My background combines physics and computer engineering: an MSc in Computer Engineering and an MSc in Advanced Physics, studies in Data Science, together with the MIT MicroMasters in Statistics and Data Science. Before the PhD I worked as a data scientist and machine learning engineer on cloud-native (AWS) systems.

• 2026 — Wave-Based Dispatch for Circuit Cutting in Hybrid HPC–Quantum Systems
  R. S. García-Raigada, J. Jorba, S. Iserte
  arXiv:2604.15279 [cs.DC]
  DQR (Dynamic Queue Router), a runtime that treats circuit-cutting fragments as schedulable units, so HPC centres can apply standard resource management to NISQ workloads. Evaluated on the CESGA Qmio supercomputer with its local QPU and the remote IBM Torino backend, with per-fragment failover to classical simulators.
