France selects Alice & Bob cat-qubit Quantum Computer for GENCI supercomputing center.

France selects Alice & Bob cat-qubit Quantum Computer for GENCI supercomputing center. June 17, 2026 PARIS, June 17, 2026 - Following the announcements made by the President of the French Republic on May 22 at the CEA's Très Grand Centre de Calcul (TGCC) regarding the second phase of France's National Quantum Strategy (SNQ), GENCI (Grand Équipement National de Calcul Intensif) and French quantum computing company Alice & Bob signed an agreement at VivaTech on June 17, in the presence of representatives of the French government, for France's acquisition of an 18-cat-qubit quantum computer. VivaTech Signing event with Michaël Krajecki, CEO of GENCI, Chloé Poisbeau, COO of Alice & Bob, and Anne Le Hénanff, Minister of AI and Digital. Photo credit: Antoine Guilloteau. This marks the world's first acquisition of a quantum computer based on cat-qubit technology. The system is part of the National Quantum Strategy under the France 2030 investment plan. The quantum computer will be hosted at the TGCC and integrated with GENCI's Joliot-Curie supercomputer. Expected to be accessible to users in 2027, the system will strengthen the strategic autonomy of France and Europe while enhancing their scientific and technological competitiveness. This quantum computer is the first so-called "early Fault-Tolerant Quantum Computer" (eFTQC) to be installed in a European computing center. Developed by Alice & Bob, the technology offers a major advantage: it natively corrects one of the two primary sources of quantum noise, known as bit-flip errors. This technological feature dramatically reduces, compared with other architectures, the number of physical qubits required to build high-performance logical qubits. As a result, it provides a natural bridge to next-generation fault-tolerant quantum computers. From 2027, the system will join the Ruby and Lucy quantum computers already installed at the CEA's TGCC facility in Bruyères-le-Châtel, where it will also be hybridized with GENCI's Joliot-Curie supercomputer. At a later stage, it will be integrated with the European exascale supercomputer Alice Recoque, acquired by EuroHPC JU, creating a hybrid platform delivering state-of-the-art computing services across high-performance computing (HPC), artificial intelligence, and quantum computing. As France prepares to access two 1,024-qubit universal quantum computing prototypes by 2032 through the PROQCIMA program of the National Quantum Strategy, led by the French Ministry of the Armed Forces, this first eFTQC system will enable users to familiarize themselves with quantum error correction and anticipate its impact on quantum computing workflows, while identifying potential applications for the technology. Like all GENCI-operated systems - including HPC, AI and quantum computing infrastructure hosted and operated within France's national computing centers - access to this eFTQC system will be provided free of charge to academic and industrial researchers conducting open research. Allocation requests will be managed through the EDARI platform. The technology was acquired through a negotiated public procurement process and is funded entirely by the HQI - France Hybrid HPC Quantum Initiative program, part of the National Quantum Strategy under France 2030. The signing ceremony took place at VivaTech on the National Quantum Strategy stand. This year marks the fourth edition of the Quantum Zone, the largest space dedicated to quantum technologies at VivaTech. As VivaTech celebrates its 10th anniversary as one of Europe's and the world's leading technology events, the National Quantum Strategy also marks its fifth anniversary. The Quantum Zone brings together the major public and private stakeholders and programs contributing to the success of France's national quantum initiative. Michaël Krajecki, CEO of GENCI, said: "The deployment in Europe of this first fault-tolerant quantum system represents a major milestone for French and European research. Starting next year, this pioneering technology, designed by Alice & Bob, will provide our researchers and industrial partners with a revolutionary tool to push the boundaries of hybrid computing, combining HPC and quantum technologies. Supported by the HQI program, this investment strengthens both our strategic autonomy and scientific excellence. It is more than just a machine: it is a promise for European innovation, open from 2027 to all those who wish to help build the future. Above all, it will offer our users the opportunity to tackle the challenges of quantum error correction, a critical step towards tangible industrial applications." Anne-Isabelle Étienvre, General Administrator of the CEA, said: "We are delighted to welcome this Alice & Bob machine to our facilities after several years of collaboration. The installation of this third HQI program machine at the TGCC demonstrates our teams' ability to host and operate some of the world's most innovative computing systems. Bringing this quantum computer into operation will provide French and European research communities with cutting-edge technology on the path towards fault-tolerant quantum computing." Dr. Théau Peronnin, Co-founder and CEO of Alice & Bob, said: "Scientific breakthroughs realise their full value when they can be deployed in real-world environments. The partnership signed today with GENCI will help bring together a community of academic and industrial researchers working to develop the technology stack required for fault-tolerant quantum computing, while broadening access to next-generation quantum technologies."

Alice & Bob launches on-premise "Helium Quantum System" for cat-qubit research.

Alice & Bob launches on-premise "Helium Quantum System" for cat-qubit research. Fault-tolerant hardware developer Alice & Bob has unveiled the Helium Quantum System, transitioning the company from chip-level manufacturing into delivering full-stack, on-premise quantum computing platforms. Operating on a noise-biased cat-qubit architecture, the integrated machine is engineered to encode the company's first logical qubit using an array of 18 physical cat-qubits. The platform is intentionally opened to global research partners, national laboratories, and high-performance computing (HPC) centers to co-develop, benchmark, and optimize quantum error-correction (QEC) protocols in live operating environments. Hardware topology, co-location integration, and operational footprint. The Helium architecture is constructed as a modular, upgradeable system designed to structurally support Alice & Bob's upcoming 48-cat-qubit chip generation without requiring complete infrastructure replacement. To facilitate deployment within legacy supercomputing nodes, the system incorporates full compatibility with major classical HPC workload managers, such as Slurm, utilizing the open-source QRMI library. For programmatic interfacing, users control the chip via Alice & Bob's native Felis software framework, which compiles custom, noise-biased instruction sets while maintaining cross-compatibility with mainstream quantum programming languages. Mechanically, the hardware reduces typical deployment barriers by operating on a modest power footprint of approximately 40 kW while maintaining strict facility tolerances, including a 18-25°C ambient temperature range, a 60 dB maximum acoustic noise threshold, and a 45-65% humidity envelope. The Starboard automations interface and platform roadmap projection. Coupled with the hardware launch, Alice & Bob introduced Starboard, a proprietary, highly automated system monitoring interface that grants site administrators real-time control over the 18-cat-qubit processor. From a centralized dashboard, operators can track individual qubit coherence metrics, program and schedule workflows based on real-time chip utilization, and review deep instrument telemetry across the cryogenic dilution refrigerator rack. This diagnostic stack serves as the foundational validation testbed for the company's long-term commercial roadmap. By leveraging the inherent phase-stabilization properties of cat-qubits - which mathematically cut hardware requirements up to 200 times compared to standard topologies - the Helium system anchors a development pipeline that routes through upcoming Lithium and Beryllium platforms, aiming to deliver a universal, fault-tolerant quantum computer by 2030. The official, joint corporate announcement and technical syndication details can be reviewed directly via the active HPCwire repository here.

Alice & Bob unveils its first quantum hardware system to advance qubit fault tolerance.

Alice & Bob unveils its first quantum hardware system to advance qubit fault tolerance. Fault-tolerant quantum computing specialist Alice & Bob SAS today unveiled its first, full-fledged hardware platform for on-premises deployments, marking its graduation from a quantum chipmaker to a complete system developer. The new Alice & Bob Helium Quantum System is designed to encode the company's first logical qubit with as little as 18 cat-qubits. The system - including the processor architecture, control electronics, cabling and software - has been architected to ensure extremely reliable quantum error correction, so users can trust its quantum calculations are correct. Alice & Bob is at the forefront of a group of European startups racing to build viable quantum computing systems, and is known for pioneering "cat-qubits," which are named after the Schrödinger's Cat thought experiment. Qubits are the main units of computing in quantum systems, similar to the "bits" found in classical computers, and have the ability to represent a 0, 1 or a superposition of both states, which is what makes them so powerful. But they're also extremely sensitive, and even something as slight as the vibration of a pin falling onto the floor could be enough to disrupt them, resulting in "decoherence" and the emergence of errors in their calculations. Cat-qubits, on the other hand, are a special kind of qubit designed to be more resistant to errors. That's because they store quantum information across multiple particles, which makes it less likely that the data they store will be corrupted. They also have a hardware-efficient design that reduces the requirements for faults to occur. Alice & Bob says cat-qubits are especially good at suppressing "bit-flip errors," which is one of the two main kinds of error that plague quantum computing platforms today. This property is key to building fault-tolerant quantum computers that can be useful in real-world applications. The Helium Quantum System is an upgradeable system that will also be able to support Alice & Bob's upcoming 48-cat-qubit chipset, which is expected to feature multiple logical qubits when it debuts next year. With its launch, the company said, it's inviting researchers to conduct experiments and collaborate with it on advancing fault tolerance for quantum machines. It supports the integration of both quantum and classical computing resources within a single system, similar to those found at high-performance computing centers. Alice & Bob is inviting research partners to conduct experiments on the Helium Quantum System and collaborate with the company on advancing fault tolerant quantum computing research. The system enables researchers to integrate quantum and classical computing resources within a single computing infrastructure, such as those found at high-performance computing centers. By providing direct access to cat-qubit architecture, Alice & Bob offers a platform for research into quantum error correction, logical qubits and the path to fault-tolerant quantum computing. Co-founder and Chief Executive Théau Peronnin said the Helium Quantum system differs from other quantum computers because the company has focused on fault tolerance from the very beginning. "Our cat-qubit architecture is designed to dramatically reduce the error-correction overhead - one of the industry's largest technical and economic barriers," he said. "We believe the defining race in quantum computing is building better qubits that can reach fault tolerance with the fewest resources." The new hardware is designed to be dropped into existing on-premises computing systems and it's incredibly energy efficient, requiring just 40 kilowatts of power to run. This helps to eliminate another major hurdle to quantum computing adoption, which is the high cost of running existing hardware systems. Alongside the physical hardware, Alice & Bob has released a custom monitoring interface called Starboard that provides full visibility into the 18-cat-qubit system. Administrators can visualize system behavior, track individual cat-qubit performance, view live metrics and schedule workloads from a single dashboard. Peronnin said the Helium Quantum System is compatible with common HPC scheduling tools such as Slurm via the open-source QRMI library and others. Image: Alice & Bob.
