As quantum training is flourishing in French Universities, several challenges arise. It is well-known that the hype around Quantum sometimes undermines the seriousness of quantum science. However, some universities have developed worldwide expertise for decades on the topic, which makes France one of the leading nations. This conference aims at deciphering the current state of quantum training in France.

This presentation will deal with the scalability of cryogenic systems dedicated to superconducting q-bit cooling in quantum data centers and will underscore the pivotal role of rethinking system architecture and refrigeration challenges in achieving the significant milestones for quantum computing infrastructure at scale. It will also present an energy benchmark for cryogenic solutions.

Quantum HF lines & harness is an important part of the QC enabling technologies due to the exponential growth of the number of Q-bit per cryostat (system scale-up) that impacts the overall performance of the system. These microwave links include Cables/Assemblies, Connector, Attenuator, Board to board and switches with specific requirements for each stage of the thermal dilution refrigerator.
To manage the scale up of the QC, high density harnesses are required like side loaders to support hundreds of lines.

One of the most promising way to scale up quantum computing is to interconnect several mid-sized quantum processing units (QPUs) in clusters. We will present the full-stack quantum link provided by Welinq to interconnect QPUs. We will discuss the scalability and adaptability of this solution and its integration in HPC environment.

Analog quantum computing is a prime candidate to highlight near-term benefits of quantum computers in an industrial setting while waiting for the Noisy Intermediate Scale Quantum (NISQ)-era to mature into its fault tolerant evulotion. Neutral atoms quantum computers (such as PASQAL’s Quantum Processing Unit) propose a new and efficient way to handle graph related problems in particular. 

Our focus for this talk will be on the analog – digital quantum computational paradigm and what is needed to achieve it, as well as on the next steps for sustainable quantum-centric supercomputing norms.

As the global leader of quantum computing, IBM is deeply engaged through its roadmap on the scaling and industrialization of our quantum computing technology.
During this presentation, we will review our current vision of the future, and share some challenges, from both hardware, software, but also adoption views.

This presentation will highlight the main challenges involved in scaling superconducting qubit quantum computers. It will explain how the IQM addresses the different aspects related to quality, quantity, and volume. And more specifically what role the future Quantum Factory in Grenoble will play in achieving these objectives.

Thanks to built-in error correction capabilities, cat qubits designed by ALice & Bob will enable to build fault-tolerant quantum computers with a comparatively small number of physical qubits.However, the design of a large-scale system brings a number of interesting challenges, at the limit of today’s capabilities.

The presentation will explore the methods and solutions that were and will be explored, taking concrete examples of Alice & Bob realizations.

The Qaptiva platform from Eviden enables the deployment of a complete quantum computing environment on an HPC cluster, with the integration of quantum processors (QPU). We will review recent deployments in national computing centers and discuss the main challenges of scaling up.

Our presentation will address the challenge of building a SaaS platform that offers quantum algorithms. Simply put, we face three key challenges in scaling up:

The challenge of market relevance, in a landscape where hardware maturity has not yet been achieved.
The challenge of skills, both in theoretical aspects (mathematics, data science, and quantum) and in navigating the diverse technological offerings, each with its own development environment.
The challenge of industrialization, as we must provide a “”as-a-service”” platform capable of functioning in “”production,”” even though most quantum capabilities currently do not offer service-level guarantees.

It is a difficult and ambitious challenge but very exciting, and we have strategies to address these different aspects.

Integration of QC within HPC compute centers is on the way, making QC a new compute paradigm. QC  offers ways to address previously unreachable problems such as NP problems. On the other hand, the integration of QC in HPC  is quite challenging, requiring the development of new middleware layers.
When considering QC, challenges appears in several domains, involving system oriented features as well as high level libraries providing building blocks for end-user to build HPC/QC ready applications. In order to address this integration, middleware should be structured and interfaces should be defined.

During this talk we’ll describe some thoughts about what’s missing to scale quantum, apart from the hardware

Quantum Computing technologies have currently a broad spectrum of solutions in terms of volume, cryogenics, mass, power consumption and, maybe, use cases they can specifically address. For a full deployment of these technologies in naval capacities (for what concerns Naval Group) in the long term, different scenarios (on premise, distributed and cloud computing) need to be considered as well as strong military environmental constraints. The scale up challenge goes together with the complex integration work which needs to be anticipated starting today in order to be able to deliver QC capacities in a not so distant future with respect to the timescale of military programs.
