Alice & Bob SAS introduced its Helium Quantum System, a full hardware solution designed to deliver fault-tolerant logical qubits through an innovative cat-qubit architecture that reduces error rates and energy demands.
- First full quantum system platform from Alice & Bob leveraging cat-qubit design
- Focuses on reducing error correction overhead for more practical quantum computing
- Supports integration of quantum and classical computing within existing HPC infrastructures
What happened
Alice & Bob SAS, a pioneer in quantum computing based in France, launched its Helium Quantum System, marking its shift from solely producing quantum chips to delivering an integrated quantum computing platform. The system encodes logical qubits using as few as 18 cat-qubits, which are specially designed qubits aimed at enhancing fault tolerance by mitigating bit-flip errors.
The Helium system includes all necessary components such as processor architecture, control electronics, cabling, and software, built to provide highly reliable quantum error correction. This launch positions Alice & Bob at the forefront of European quantum startups, providing a platform for researchers to experiment and collaborate on improving quantum fault tolerance.
Why it matters
Quantum computing’s potential is hindered by the fragility of qubits, which are prone to errors from even minute environmental disturbances. Cat-qubits used by Alice & Bob store information across multiple particles, enhancing resilience against such disturbances and significantly suppressing bit-flip errors—a critical challenge for practical quantum computers.
By significantly reducing the error-correction overhead, the Helium Quantum System promises a more resource-efficient path to fault tolerance, which has been a major technical and economic barrier in the quantum computing industry. Moreover, its energy-efficient design requiring only 40 kilowatts of power helps lower operating costs and supports easier adoption in existing on-premises and high-performance computing (HPC) environments.
What to watch next
Alice & Bob plans to support an upcoming 48-cat-qubit chipset that will allow for multiple logical qubits, expected to debut next year. This will provide an expanded platform for advancing quantum computing capabilities and fault tolerance. Researchers and collaborators are encouraged to utilize the Helium Quantum System to explore quantum error correction and logical qubit development.
The system features a new monitoring interface, Starboard, which offers comprehensive oversight of qubit performance and system metrics, integrating with common HPC tools like Slurm. Industry observers should monitor how well Alice & Bob’s platform integrates quantum and classical resources in real-world settings and how effectively it accelerates the development of practical, fault-tolerant quantum computers.
