The compact, upgradeable system integrates an 18 noise-biased cat-qubit chip with degree-2 connectivity and a dedicated control interface, enabling researchers to explore hardware-efficient paths to early fault-tolerant quantum computing. The development is backed by the company’s €130 million ($142 million USD) in total funding and a recently announced $50 million product development laboratory in Paris designed to accelerate prototyping of next-generation chips.The Helium platform serves as a purpose-built error correction laboratory centered on a multi cat-qubit architecture. Cat qubits are superconducting qubits engineered with strong noise bias that intrinsically suppresses bit-flip errors, allowing error correction codes to concentrate resources on phase-flip errors and thereby reducing the physical qubit overhead required for logical operations.Key technical parameters include:By opening the Helium platform to external research teams, Alice & Bob is accelerating validation of its cat-qubit approach while building collaborative momentum toward practical FTQC systems. The company has shown that its architecture can reduce hardware requirements for useful large-scale fault-tolerant quantum computers by up to 200 times compared with conventional superconducting platforms.This efficiency drives the commercial roadmap. A 4,000 m², $50 million purpose-built laboratory in Paris—equipped through partnerships with Quantum Machines for hybrid control solutions and Bluefors for a cryostat farm supporting up to 20 dilution refrigerators—will host nanofabrication capabilities and dedicated space for next-generation chips. The facility will support development of the Lithium and Beryllium generations leading to Graphene, a 100-logical-qubit quantum computer planned for 2030.By enabling rapid prototyping and client-accessible testing environments, the Paris lab positions Alice & Bob to move cat-qubit systems from laboratory demonstrations toward market-ready products with substantially smaller footprints, lower energy demands, and reduced infrastructure requirements, facilitating earlier integration with high-performance computing workloads.Find out more here.Further articles, reports, and the latest quantum computing news may be found at The Qubit Report.Horizon Quantum is establishing its second quantum computer testbed in Dublin, Ireland, equipped with an IonQ 256-qubit trapped-ion system.
