Abstract: Incorporating Quantum Computing (QC) into High Performance Computing (HPC) environments (commonly referred to as HPC+QC integration) marks a pivotal step in advancing computational capabilities for scientific research. This paper provides a firsthand account of integrating a superconducting 20-qubit quantum computer into the HPC infrastructure at [InstitutionAnonymizedForReview], one of the first practical implementations of its kind. This yielded four key lessons: (1) quantum computers have stricter facility requirements than classical systems, yet their deployment in HPC environments is feasible when preceded by a rigorous site survey to ensure compliance; (2) quantum computers are inherently dynamic systems that require regular recalibration that is automatic and controllable by the HPC scheduler; (3) redundant power and cooling infrastructure is essential; and (4) effective hands-on onboarding should be provided for both quantum experts and new users. By sharing these experiences, we aim to provide a roadmap for other HPC centers considering similar integrations.
