The installation of quantum machines at the CEA brings new constraints for the host infrastructure.

The specific requirements in terms of technical services can be quite different from what is usually found in an HPC computing center.

The presentation will outline what has been achieved at the TGCC to address these new issues inherent to quantum computers.

Feedback on the integration of an IQM Spark 5 quantum computer into Eviden’s HPC laboratory based in Angers.

Highlighting environmental constraints, site preparation, installation, calibration, and long-term hosting.

This talk outlines prerequisites for integrating quantum computers into existing HPC environments.

Apart from the obvious, technical requirements an overview is given on the application use cases of state-of-the-art quantum computers, and linking software and abstraction layers.  

We are conducting JHPC Quantum project to design and build a quantum-supercomputer hybrid computing platform by integrating different kinds of on-premises quantum computers, IBM superconducting quantum computer and Quantinuum trapped-ion quantum computer, with several supercomputers including Fugaku.

Recently, we have installed these two quantum computers in Kobe and Wako respectively in Japan, and start the operation of our platform. In this talk, the installation and operation of these two quantum computer are presented with the current status of our project.

As quantum computing matures towards FTQC, deploying systems on-premise is becoming a key milestone for early adopters. This session highlights the engineering and software challenges of hosting superconducting cat-qubit systems in real datacenter environments.

We’ll examine the co-design between cryogenic hardware, control stack, and software interfaces that ensure stable, scalable, and secure operation.

JHPC-Quantum is one of the projects to integrate Quantum and HPC systems.

We started test operations from last year. In this presentation, we present our implementations, the experiences gained and the improvements made through one year of real operation.

QPerfect’s MIMIQ is a high-performance quantum emulator built on advanced tensor network (MPS) techniques. This talk will present technical insights from developing and benchmarking MIMIQ, demonstrating its capability to simulate large-scale algorithms with thousands of qubits.

We will discuss the key lessons learned from optimizing tensor network simulators for performance and flexibility, including the ones that enabled our recent simulation of large-scale logical quantum algorithms and how emulation is helping QPerfect working on compilation and software tooling to bridge the gap between high-level algorithm design and hardware.

As it comes to integrate Quantum Computers in actual machine rooms, many obstacles are on the path. Beyond hardware related issues, software integration is a major challenge to be addressed in order to make it possible to compute on the QPU from the users environment where they access classical and quantum compute resources.

This topic describes how Qaptiva can be used to integrate QPUs in compute center with a focus on a real use case : the integration of the Lucy QPU, provided by Quandela into CEA’s TGCC compute center. 

Integrating multiple QPUs into an established HPC environment provides unique opportunities – and challenges – for both users and system designers. We present the lessons learned from enabling access to a diverse set of quantum resources, including a photonic QPU (Lucy), a neutral-atoms QPU (Ruby), and a classical simulator (Qaptiva), from an existing Slurm-based HPC infrastructure.

The integration enables classical workloads to invoke quantum resources transparently, while a dedicated Slurm instance manages the QPU platform itself. From an applicative perspective, this effort highlights that hybrid HPC-quantum environments remain an emerging and rapidly evolving field. Supporting a new user base – often unfamiliar with HPC workflows – requires dedicated onboarding, documentation, and tooling.

Furthermore, achieving coherence among multiple rapidly-evolving vendor-specific software stacks within a unified environment proved to be a key technical and organizational challenge. This experience underlines the importance of adaptable middleware, clear abstractions, and close collaboration between HPC and quantum teams. As the boundaries between classical and quantum computing continue to blur, such lessons are essential to designing scalable, user-friendly hybrid infrastructures that can evolve with the next generation of quantum technologies.

The EuroHPC Joint Undertaking has federated six Hosting Entities, and their 24 partners from 17 European countries to build a joint project for the respective integrations of six different quantum computers with six supercomputers.

This hybrid infrastructure will benefit European open research communities and integration should thus be harmonized across the different sites. Sabine Mehr, as coordinator of the project, and Martin Schulz, who is leading the technical harmonization, will give you an overview of the planned actions of this project, as well as a perspective on the available technologies. 

Earth observation has inevitably arrived in the Big Data era, but the high requirement on computation power inherently requires HPC systems to tackle the tasks that drive the development of EO systems:

Disaster Management, Urban Development, Public Health or Education.

On the other hand, computational power is already a bottleneck for analyzing large amounts of remote sensing data with sophisticated machine learning models.

Thus, we show how quantum computing can contribute to a solution to tackle this challenge by leveraging quantum properties and explore the requirements of the EO use case for hybrid HPC-QC systems.

Step into the quantum journey with OVHcloud and discover how Europe’s leading cloud provider is making quantum computing accessible to industries and researchers through an open, sovereign, and interoperable platform.

This session will also feature a live integration case : the collaboration with Serco, connecting OVHcloud’s Quantum Platform to the European DestinE (Digital Twin Earth) portal, leveraging quantum power to process and analyze Earth observation data.

Join us to explore how this approach paves the way for the next generation of hybrid computing pipelines, driving European innovation.

We propose the Many-body Quantum Score (MBQS), a practical and scalable application-level benchmark protocol designed to evaluate the capabilities of quantum processing units (QPUs) – both gate-based and analog – for simulating many-body quantum dynamics. MBQS quantifies performance by identifying the maximum number of qubits with which a QPU can reliably reproduce correlation functions of the transverse-field Ising model following a specific quantum quench.

In this talk, I will present the MBQS protocol and highlight its design principles, supported by analytical insights, classical simulations, and experimental data. I will also share preliminary results obtained with Ruby, an analog QPU based on Rydberg atoms developed by Pasqal, which is soon to be deployed at the TGCC. These findings demonstrate MBQS’s potential as a robust and informative

In this talk, we will explore why applicative benchmarking matters from a user’s perspective and how it evaluates nearly all aspects of execution on a Quantum Processing Unit (QPU), from qubit and hardware quality to the intricacies of compilation and transpilation tools, as well as state-of-the-art methods for adapting algorithms to specific platforms.

We will demonstrate these concepts using the BACQ benchmarking framework and the DWave family of processors.

After an introduction on the availability requirements of our computers, we present the installation and acceptance procedures for our infrastructures from delivery to service launch.

We conclude with the maintenance procedures

A number of quantum computers are now installed in Europe, Asia and the US, in HPC centres, at cloud providers and on private sites.

We are interested in hearing from some of these players about their experiences and how the integration and validation stages went. Sharing this feedback can benefit hosting sites, future hosts and suppliers alike.
