Alice & Bob Tech Stack

Cat-qubit quantum processors with intrinsic error correction

Computer Hardware Manufacturing Paris, Île-de-France 51–200 employees Founded 2020 Privately Held

Alice & Bob manufactures superconducting quantum processors using a proprietary cat-qubit architecture designed for fault tolerance at scale. The company is migrating infrastructure from Docker to Kubernetes while building out observability (Grafana, Prometheus, InfluxDB) and automating financial/manufacturing workflows — operational moves typical of a hardware company scaling from prototype toward production. Engineering dominates the hiring mix, with active recruitment in calibration APIs and fault-tolerant architecture, reflecting the technical depth required to reduce chip fabrication lead times and QPU performance variability.

About Alice & Bob

Alice & Bob designs and manufactures quantum processors based on cat qubits, a superconducting qubit topology claimed to reduce error-correction overhead by up to 200× versus conventional approaches. Founded in 2020 and headquartered in Paris with a Boston office, the company operates as a hardware-focused R&D organization with 120+ employees across 17+ countries. Current priorities span manufacturing engineering (backend-of-line automation), quantum architecture (fault-tolerance at scale), and operational infrastructure (treasury, observability, financial systems). Active projects target 2027+ chip roadmaps while addressing near-term production bottlenecks in measurement resource scaling and amplification chain capacity.
