Operating quantum hardware in an HPC environment: potential, challenges, lessons learnt
There is broad consensus that the utilisation of quantum computers, both in the current Noisy Intermediate‑Scale Quantum (NISQ) era and in future fault‑tolerant systems, will not rely on stand‑alone machines but on hardware integrated into heterogeneous high‑performance computing (HPC) platforms. In this context, quantum computers will act as a specialised class of accelerators, complementing other dedicated resources within larger computational workflows. Guided by these principles, the Leibniz Supercomputing Centre has been developing an integration strategy for hybrid HPCQC systems, covering hardware, software, and operational aspects. In this talk, I present an overview of the experience gained from operating the first quantum systems at LRZ, which began in 2024. Particular focus is given to the early operation of Euro‑Q‑Exa, a superconducting quantum system with 54 qubits that entered its Friendly User Pilot Phase in March 2026. Usage statistics, selected use cases in computational chemistry and optimisation, and insights into user interaction with a cutting‑edge computing resource are discussed. Finally, as quantum hardware continues to advance in performance and scale and becomes increasingly integrated with modern, AI‑enabled supercomputers, emerging synergies between HPC and quantum computing, particularly in areas such as quantum error detection and correction, provide confidence in the long‑term applicability of this technology.
