This “half a day” workshop will address some of these topics as it aims to depict the available pieces of software that will help in integrating an actual quantum computer inside a machine room, making it available to end users.
This workshop is a follow-up of the first edition of the QRUCH workshop which took place during ISC'25. This workshop was itself a follow-up to the BoF “Towards Hardware Agnostic Standards in Hybrid HPC/Quantum Computing” at ISC’24.
Quantum Computing is not a completely new topic: it was introduced in 1981 during a conference at MIT, but it really came under the spotlight as Peter Shor released his famous algorithm capable of breaking RSA encryption with tremendous acceleration. The domain remained a bit theoretical, studied in mathematical computer science, until a few years ago when actual Quantum Computers arrived on the market providing real (but yet limited) quantum compute resources. In the very last years, Quantum Computers gained more compute power, and they started to be deployed inside HPC centers while also becoming available on cloud based platforms.
As Quantum Computers leave the laboratories where they were designed and enter the HPC machine room, it becomes necessary to consider how they can be used to perform actual computation on real life use cases. As we are still in the NISQ era, and because HPC resources may help in using Quantum Computers efficiently, the hybrid HPC/QC naturally appeared, providing acceleration similarly to GPU previously.
This is not as easy as it seems. As the hardware becomes ready to be installed in computer rooms, the software stack has not evolved as fast. In particular, the required software stack to “glue” HPC and QC is not fully defined. Solutions exist and are provided by both research institutes and vendors, but they obey no standard.
Current Quantum Computers are provided with a very simple software stack, usually a Python based framework, providing native access to the computing resources as well as a “mock device” providing emulation on standard CPU (and sometimes GPU) compute power. As we consider the integration inside the computer center, many topics, related to system integration as well as application integration are to be considered, such as:

ADD HERE THE DESCRIPTION OF THE KEYNOTE TALK
The Barcelona Supercomputing Center is actively developing the infrastructure and tooling required to integrate quantum computing into large-scale HPC environments. This lightning talk will present an overview of our ongoing efforts within Qdislib, including distributed quantum circuit cutting, advances in quantum circuit caching strategies, experiments connecting HPC systems with on-site and cloud-based QPUs, and the design of dedicated hybrid schedulers..
The deployment of EuroHPC PIAST-Q, a trapped-ion quantum computer integrated with classical high-performance computing resources at Poznan Supercomputing and Networking Center was an important shift toward hybrid quantum-classical infrastructure capable of serving multiple users and diverse computational modalities. With this architecture, users access a unified environment enabling classical CPUs, GPUs and quantum processing units (QPUs) concurrently. By enabling broad access across academia, industry and the public sector, this infrastructure fosters a new class of workflows that exploit multi-modality computing in a shared environment, and accelerating hybrid-quantum application development
The integration of quantum computers within classical High-Performance Computing (HPC) infrastructures is receiving increasing attention, with the former expected to serve as accelerators for specific computational tasks. Differences in hardware architectures, communication models, and programming workflows introduce nontrivial integration issues. Even more critically, the scarcity of quantum devices, especially compared to the large number of classical nodes in modern HPC systems, creates an inherent scheduling bottlenek. We propose a novel malleability-based approach to optimize resource utilization in hybrid HPC–quantum workloads. This dynamic strategy enables workloads to adjust their resource footprint at runtime depending on the availability of quantum resources.
While the convergence of AI and HPC continues to accelerate, quantum computing is emerging as a new computational resource. ABCI-Q is a unique hybrid platform that integrates a GPU-based AI supercomputer with three types of quantum computers — superconducting, neutral atom, and photonic. This talk introduces the concept, implementation, and current status of ABCI-Q, highlighting its role as a prototype for future AI–quantum–HPC integration and discussing the emerging challenges and opportunities in hybrid computing.
Coffee Break (synchronised with ISC'25 coffee break)
Optimization problems are ample in maritime logistics and especially for mixed integer linear problem formulations depend a lot on the modelling. Thus, domain expertise is needed in order to find a realistic problem definition while keeping the current limitations of the QC hardware in mind. I will present for several important optimization problems in maritime logistics decomposition methods as the Benders decomposition, its advantages and the requirements these hybrid workflows pose on the QC/HPC hardware.
This talk introduces the Juelich UNified Infrastructure for Quantum computing (JUNIQ), gives an overview of the currently available QC hardware and the ongoing HPC-QC integration efforts at JSC and closes with some thoughts on how future implementations of HPC-QC integration could look like.
The EuroQHPC-Integration project is funded by EuroHPC. It is coordinated by GENCI, brings together 30 partners, spread across 17 European countries, and relies on 6 quantum computers with various architectures (neutral atoms, superconducting qubits with different topologies, quantum annealing, photonics, trapped ions) that will be coupled with 6 European supercomputers forming an unprecedented hybrid HPC/QC infrastructure. This topic will highlight the main topics of this project.
