Alice & Bob, a quantum computing company, and the Science and Technology Facilities Council’s (STFC) Hartree Centre have announced a collaboration to integrate Alice & Bob’s future QPUs with high-performance computing (HPC) environments via SLURM. SLURM is the widely used workload management system for supercomputers. The integration is intended to make Alice & Bob’s cat-qubit technology compatible with existing HPC workflows, allowing quantum processors, GPUs, and CPUs to be comanaged by the workload management system. SLURM allocates computing resources and schedules jobs to run efficiently, which is critical for maximizing throughput in hybrid quantum–classical workflows. Alice & Bob specializes in cat [...]

Alice & Bob, a quantum computing company, and PLASSYS-BESTEK, a supplier of vacuum deposition systems, have announced the delivery of the SQUID-6 UHV deposition system to Alice & Bob’s new advanced quantum lab in Paris. This delivery is part of the ULTRACAT project, which is supported by France’s Defense Innovation Agency (AID). The SQUID-6 UHV is a new, fully automated, ultra-high vacuum (UHV) deposition system designed to enable next-generation quantum chip nanofabrication. It employs a modular cluster architecture working around a central UHV distribution chamber, allowing for the serial processing of multiple wafers up to 8 inches in diameter. This design [...]

Alice & Bob has announced new research results showing that their cat qubits can resist one of the main errors in quantum computers, the bit-flip, for more than one hour. The company measured hour-long bit-flip times, a considerable advance over the previous record of 430 seconds (about seven minutes) set in 2024. The results were achieved on the company's latest qubit design, the Galvanic Cat, which is used on their Helium 2 chip. At a mean photon number of 11, the team was able to measure bit-flip times between 33 and 60 minutes with a 95% confidence interval. The experiment also [...]

Alice & Bob has integrated NVIDIA’s CUDA-Q quantum development platform into its open-source Dynamiqs simulation library. CUDA-Q provides hybrid quantum–classical computing capabilities, while Dynamiqs is optimized for GPU acceleration to simulate time-dependent quantum systems. Early benchmarks show the combined toolchain can achieve up to 75x speed improvements over conventional simulation frameworks when modeling large-scale quantum dynamics. The integration allows Dynamiqs to simulate complex, rapidly evolving quantum processors more efficiently. By offloading tasks to GPUs, researchers can perform large-scale simulations and parameter sweeps across diverse conditions, significantly reducing compute time. Alice & Bob’s development team collaborated with NVIDIA to create APIs that [...]

Alice & Bob has been selected for the French Tech Next40, the French government’s strategic support program for high-growth technology companies. This marks the first inclusion of a quantum computing firm in the initiative, which targets startups demonstrating significant commercial traction through revenue or capital raised. The selection places Alice & Bob within a national framework designed to accelerate scaling and internationalization of France’s most advanced tech firms. The company qualified based on its €130 million in fundraising between 2022 and 2025, and will receive tailored support from the Mission French Tech team and affiliated public agencies. Services include regulatory assistance, [...]

Alice & Bob has announced the construction of a $50 million quantum hardware facility in Paris, featuring a 4,000 m² chip development lab with a nanofabrication cleanroom and infrastructure to support its next-generation QPU lines: Lithium, Beryllium, and Graphene. The facility will include a cryostat farm housing 20 dilution refrigerators to enable parallel experimentation and development, with a dedicated section for testing Graphene, a 100-logical-qubit machine scheduled for 2030. The lab is funded by the company’s recent $103 million Series B. The site will integrate systems from Quantum Machines and Bluefors, who will provide quantum control electronics and cryogenic infrastructure, respectively. [...]

Alice & Bob, a leader in fault-tolerant quantum computing, has announced a significant advancement in cat qubit technology, achieving a 160x improvement in bit-flip error protection through a technique called “squeezing.” This innovation, detailed in a recent preprint, optimizes error suppression by compressing the quantum state of cat qubits, reducing the need for resource-intensive error correction. Cat qubits, a type of superconducting qubit, are designed to minimize bit-flip errors by increasing the separation between quantum states. However, this typically comes at the cost of increased phase-flip errors. By squeezing cat qubits, Alice & Bob has demonstrated a method to enhance bit-flip protection without compromising phase-flip performance. In experiments, squeezed cat [...]
