The Quantum Europe Strategy aims to position Europe as a leader in quantum technologies, driving innovation and competitiveness.

This presentation explores its goals, including research funding, public-private partnerships, and workforce development, while highlighting the semiconductor industry’s pivotal role in advancing quantum technologies.

Hitachi is developing silicon quantum computer system based on the results of fundamental research of high-fidelity qubit operations with collaboration with academia.

Cryo-CMOS chips were developed for large-scale integration of qubits that will bring breakthrough to the system.

A new qubit chip configuration was proposed to implement quantum error correction with shuttling operation.

Hierarchical architecture with cryo-electronics was implemented which is utilized for efficient qubit control.

Scaling quantum computing is not only a qubit problem. Every quantum processor needs classical computing alongside it — to control it, to correct its errors in real time, and to make it programmable.

Today each builder constructs that layer alone. This talk asks what it would take to share it, and how NVIDIA’s work on open interfaces between quantum processors and accelerated computing could help European players industrialise.

Spin qubits in semiconductor quantum dots, proposed in 1998 [1], are a leading platform for quantum computing: long coherence, small footprint, and industrial fabrication.

The first part of the talk reviews the field of spin qubits and the path to scalability [2], including micromagnet-free control of electron spins in Si/SiGe [3].

The second part shows that the same hardware supports classical reversible logic: coherent spin dynamics with classical inputs and outputs, no algorithmic use of superposition, and no erasure until readout, so the Landauer bound does not apply to the logic [4].

The building block is an iToffoli gate driven by DC pulses, with a gate energy below the Landauer scale at 4 K, about five orders of magnitude below a CMOS Toffoli including cooling overhead.

Motivation: the rising energy demand of data-center and AI workloads.

The lead time to build quantum capability exceeds the lead time to build the hardware.

Allianz Quantum Hub acts on that gap: a group-level team running experiments with external partners on business challenges, under its build-value and build-network pillars.

The talk covers the roadmap across three horizons, from this year’s deliverables to the validation any production use would require, and the projects in catastrophe modelling, cyber anomaly detection with quantum machine learning, and asset-liability management.

It closes on how an insurer values a startup before working with it, and when those criteria expire.

Spin qubits in Si/SiGe have recently demonstrated reproducible in-system two-spin gate fidelities well above 99.9 % and the compatibility with industrial fabrication, thus reaching or exceeding performance parity with other platforms.

I will review this progress and survey our competitive European effort on this platform.

Europe is world leading in electron shuttling, which is expected to play a key enabling role for realizing larger systems.

This innovation at the quantum layer is complemented by a detailed concept for reaching utility-scale systems.

Quantum computing only delivers real value once it scales to around one million qubits.This talk presents QSOI®, Quobly’s silicon spin-qubit technology with control logic co-integrated on a single chip, and the industrial partnership with STMicroelectronics.

Derived from ST’s proven 28FDSOI process and manufactured in a 300mm fab, QSOI® is designed for efficient, high-volume production. The presentation walks through the QPU architecture via a product schematic, shares the latest technology and qubit performance results, and outlines the joint roadmap.

France’s 5-year-old National Quantum Strategy, initially funded with €600 million, has been boosted by an additional €1 billion in 2026.

This acceleration aims to double investments in key programs, target 1,000 logical qubits by 2032, and strengthen European sovereignty in quantum technologies.

The focus is on scaling infrastructure, software, and collaboration to ensure leadership in this critical field.

Electronics, and in particular integrated photonics, are key enabling technologies for the development and scaling of quantum applications. As quantum technologies move from research to industrial applications, they will generate specific supply chain requirements that differ from those driving today’s electronics industry, including datacom, AI and consumer electronics.

With its strong technological capabilities, industrial base and concentration of research and innovation actors, Paris region is uniquely positioned to contribute to the emergence of this new quantum supply chain.

The region is actively working to foster the development of this ecosystem and support the emergence of a strong quantum supply chain in France and across Europe.

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.
