$50m quantum computing lab for Paris
Cette publication existe aussi en Français
Startup Alice & Bob is building a $50m quantum computing laboratory in Paris to support the development of its products with up to 100 logical qubits.
The company, which develops cat qubits, is working with Quantum Machines for the hybrid control systems and cryogenic systems manufacturer Bluefors.
The new lab will enable Alice & Bob’s next-gen quantum chip series: Lithium, Beryllium and Graphene, and is funded by the company’s recent $103m Series B funding round. The Helium 16qubit processor taped out back in 2023, but the 100 logical, error corrected qubits will require thousands of physical qubits.
The 4,000 m2 purpose-built product development hub will host a nanofabrication cleanroom for the prototyping advanced QPUs and a cryostat farm with 20 Bluefors dilution refrigerators.
“Our state-of-the-art product development lab will serve as a cornerstone of French quantum infrastructure and as a blueprint of how to build industrial-scale tech in Europe,” said Théau Peronnin, CEO of Alice & Bob. “As our company’s focus is shifting from pure research to commercialization, our lab will enable Alice & Bob to create technology that can be tested by actual clients and end users.”
A dedicated area of the cryostat farm is reserved for the installation of the company’s large-scale quantum computer Graphene, a quantum computer with 100 logical qubits planned for 2030. Quantum computers built on cat qubits scale more efficiently with an ability to suppress bit-flip errors as described in eeNews Europe here.. This allows more complex machines in a smaller footprint and with less energy requirements.
“As the control provider for more than half of companies developing quantum computers globally, we’re involved in many ambitious initiatives,” said Dr. Itamar Sivan, co-founder and CEO of Quantum Machines. “This lab stands out as one of the most innovative projects. Alice & Bob’s hardware-efficient approach creates a unique path to fault-tolerant quantum computing that could dramatically reduce the resources needed for utility scale quantum error correction.”
“Alice & Bob’s hardware-efficient cat qubit is a very interesting application for Bluefors cryogenic solutions, which also support more stable and efficient quantum systems,” said David Gunnarson, Bluefors’ Chief Technology Officer. “We are excited to work with Alice & Bob to deploy our dilution refrigerator measurement systems to push quantum technology even further, underscoring our commitment to advance the quantum computing industry with cryogenic systems of the highest standard.”
“This facility marks a major milestone for the French quantum industry,” said François Charbonnier, Investment Director at Bpifrance. “By anchoring its accelerated quantum chip development cycle in Paris, Alice & Bob is positioning itself – and Europe – as a leader in delivering real-world breakthroughs.”
