From HPC to Quantum at IT4Innovations

Abstract

This paper surveys the computing continuum at IT4Innovations (IT4I) from petascale supercomputers (Karolina, Barbora/Barbora NG) and pilot platforms to visualisation VR/labs and the VLQ quantum computer together with user access schemes, training programmes, and applied research outputs. It outlines the centre's role in the Czech e-infrastructure (e-INFRA CZ), its participation in the EuroHPC ecosystem (including LUMI and forthcoming AI-capable services), and the integration path for hybrid HPC{QC work ows. We summarise representative user impacts across academia, industry, and public administration; describe service routes (Open Access, institutional/community, fast-track, industrial cooperation); and highlight recent project results (LEXIS platform, HEAppE, HyperQueue, MERIC, ESPRESO, Floreon+), illustrating how platform engineering and methodology transfer accelerate uptake and readiness for next-generation systems. Finally, we position Europe's HPC landscape relative to the United States and outline near-term directions: commissioning Barbora NG, scaling AI-ready services thanks to LUMI AI Factory, and operationalising VLQ within EuroHPC federated work ows
