Alice & Bob 押注猫量子比特，让容错量子计算切实可行；获 1.04 亿美元 B 轮融资，推出 Helium 系统

做的是什么生意

Designs and sells fault-tolerant quantum computers built on superconducting cat qubits that natively suppress bit-flip errors, starting with research systems for HPC centers.

启动资金：€100M ($104M) Series B, January 2025, co-led by Future French Champions, AXA Venture Partners and Bpifrance (TechCrunch); valuation reported at $300–400M.

起因

Founded in 2020 in Paris by physicists Théau Peronnin and Raphaël Lescanne, spun out of ENS and Inria research on Schrödinger-cat states in superconducting circuits; the founders set fault tolerance as the goal from day one.

经过

Raised a €27M Series A in 2022 (TechCrunch). In January 2025 it closed a €100M Series B; investors said the 'R&D phase is over' as chip architecture headed toward 48 qubits. In June 2026 it unveiled Helium, its first complete on-premise quantum system encoding a logical qubit with 18 cat qubits, and signed GENCI to deliver France's first cat-qubit computer.

结果

Scaling: Helium launched 2026-06-10 and GENCI's 18-cat-qubit system is expected to open to researchers at CEA's TGCC in 2027; the 48-cat-qubit chip with multiple logical qubits is on the roadmap.

可借鉴之处

当整个行业争相增加量子比特数量时，初创公司可以通过改变物理设计来取胜，让最困难的部分（纠错）变得便宜，而不是用更多硬件硬碰硬。
