Atom Computing的原子押注：1225个量子比特，首个逻辑量子比特销售，融资3亿美元

做的是什么生意

Atom Computing builds quantum computers from optically trapped neutral atoms (ytterbium nuclear-spin qubits) in large arrays, selling on-premises systems aimed at fault-tolerant, utility-scale computing for chemistry, materials, and optimization workloads.

启动资金：Over $300M cumulative, including a $100M Series C led by Third Point Ventures with DCVC and Cisco Investments, plus a $100M Letter of Intent from the U.S. Department of Commerce (June 2026)

起因

Physicist Ben Bloom founded Atom Computing in 2018 after years of neutral-atom research; Rob Hays led as CEO through its early rounds. The thesis was that laser-held neutral atoms with nuclear-spin qubits could scale past superconducting machines without lithographic fabrication limits.

经过

In October 2023 Atom Computing announced a 1,225-site array populated with 1,180 qubits — the first universal gate-based system past 1,000 qubits. In November 2024 it launched a commercial machine with Microsoft: Atom hardware plus Microsoft's qubit-virtualization module, shipped through Azure Quantum. In July 2025 Denmark's EIFO and the Novo Nordisk Foundation committed €80M to QuNorth, which ordered Magne — a Level 2 machine with 1,225 physical and 50 logical qubits, built by Atom Computing and Microsoft, construction starting autumn 2025.

结果

In June 2026 Atom Computing demonstrated the first full quantum error correction with a toric code on neutral-atom hardware, reporting logical error rates that drop as qubit count scales; it also crossed $300M cumulative funding with a $100M Series C and a $100M Commerce LOI, and passed into Stage B of DARPA's Quantum Benchmarking Initiative.

可借鉴之处

硬件押注通过选择正确的扩展曲线而非跟随现有工艺而获胜：初创公司可以在更陡峭、更便宜的轨迹上超越巨头。
