A new integration pathway for quantum computers into existing high-performance computing (HPC) centres has been demonstrated by Lukas Burgholzer and colleagues at Technical University of Munich. The pathway uses the Quantum Device Management Interface (QDMI), addressing the complexity arising from vendor-specific software chains. Implementing a QDMI layer with IQM superconducting systems and connecting it to Slurm job execution and Qiskit workflows sharply reduces the bespoke engineering required for each quantum backend. The resulting standardised software-hardware boundary provides reusable software components across different providers and deployment styles, enabling a faster transition from quantum pilots to production workflows. Standardised interface dramatically reduces quantum software development overhead The implementation reduces custom engineering effort by 75%, a figure previously unattainable due to the lack of standardised interfaces between quantum hardware and high-performance computing systems. This substantial reduction in effort is critical because the development of quantum algorithms and applications is already a complex undertaking, and the added burden of hardware-specific integration significantly hinders progress. Prior to this work, integrating a new quantum processor into an HPC environment often necessitated a complete rewrite of interfacing software, consuming valuable time and resources. This 75% reduction allows development teams to focus on algorithm design and optimisation, rather than low-level hardware communication. This threshold enables genuinely reusable software stacks, moving beyond isolated pilot projects and allowing scalable quantum integration within HPC centres. Previously, each quantum backend demanded entirely new software development, creating a significant operational burden, particularly for centres aiming to offer quantum computing as a service to a broad user base. Central to this advancement is the Quantum Device Management Interface, or QDMI, which functions as a universal translator between quantum processors and conventional computing resources, decoupling software evolution from specific hardware characteristics. QDMI achieves this by defining a consistent set of application programming interfaces (APIs) for
