This paper proposes a full-stack layered architecture for Quantum Integrated High-Performance Computing (QHPC), positioning quantum processing units as first-class accelerators within classical HPC stacks rather than peripheral add-ons. The framework emphasizes tight on-premise coupling through unified resource management, quantum-aware scheduling, and abstraction layers that allow users to submit heterogeneous workloads via a consistent interface similar to Slurm. By targeting applications in quantum chemistry, materials discovery, and climate modeling, the architecture aims to solve scalability challenges essential for building reliable, programmable future ecosystems.
Quantum Integrated High-Performance Computing: Envisioning a Layered Architecture for Next-Generation Hybrid Computing Infrastructure
arXiv:2604.19814v2 Announce Type: replace Abstract: High-performance computing (HPC) has evolved over decades through multiple architectural transitions, from vector supercomputers to massively parallel CPU clusters and GPU-accelerated systems, continuously expanding the frontier of scientific discovery. With the emergence of quantum processing units (QPUs) as practical computational accelerators, a new opportunity arises to further extend this trajectory by integrating quantum and classical computing paradigms. Building on the emerging vision of Quantum Integrated High-Performance Computing (QHPC), this paper contributes a full-stack layered architecture that integrates QPUs as first-class accelerators within, not merely alongside, the classical HPC software and hardware stack, with tight, on-premise quantum-classical coupling as its defining characteristic. The architecture comprises of unified resource management, quantum-aware scheduling, hybrid workflow orchestration, middleware and programming abstraction, interconnect technologies, and a tiered execution model enabling seamless workload partitioning across classical and quantum backends. A central aspect of this architecture is a strong user requests abstraction layer that exposes heterogeneous resources through a unified job submission interface, similar in spirit to existing schedulers such as Slurm, allowing users to describe workloads in a consistent template independent of underlying compute type or location. Drawing insights from prior accelerator integration eras, we outline how QHPC can support emerging workloads in quantum chemistry, materials discovery, combinatorial optimization, and climate modeling. We conclude by highlighting open challenges in building scalable, reliable, and programmable quantum-classical infrastructures that seamlessly connect global users to heterogeneous compute resources for future quantum-classical HPC ecosystems.
