Company profile
researched Aug 2026Atom Computing is a quantum computing hardware company founded in January 2018 and headquartered in Berkeley, California, with a data center in Boulder, Colorado that hosts several of its systems. It builds universal, gate-based quantum computers using arrays of optically-trapped neutral atoms, encoding qubits in the nuclear spin states of ytterbium-171 atoms that are cooled, trapped and controlled with lasers rather than individual electrical wiring.
Its commercial platform, AC1000, is a universal gate-based system offered for on-premises installation. Published specifications include more than 1,200 physical qubits, all-to-all connectivity, one-qubit gate fidelity above 99.9%, two-qubit gate fidelity above 99.6%, SPAM fidelity above 99.8%, movement fidelity above 99.9%, parallel gate operations and movements, mid-circuit measurement with qubit reset and reuse, real-time conditional branching, OpenQASM/QIR APIs and a 20-qubit emulator. The system occupies roughly 600 sq ft (56 m2) with moderate power requirements, allowing installation in existing office buildings. The platform is positioned for quantum error correction research and the construction of logical qubits; one report describes the AC1000 as supporting around 30 logical qubits.
The company's stated scaling thesis is that neutral-atom arrays can be expanded toward thousands or millions of qubits without substantially changing the system footprint, with roughly an order-of-magnitude increase in qubit count per generation, targeting over 10,000 physical qubits and more than 100 logical qubits in the next generation.

launches, deals, and filingsStrategic collaboration with Nu Quantum to build hardware for scaling neutral-atom quantum computers toward utility scale.
The company announced total funding of more than $300 million, comprising a $100 million Series C led by Third Point Ventures with participation from DCVC, Cisco Investments and others, and a signed Letter of Intent with the U.S. Department of Commerce for $100 million. Funds are directed at scaling qubit counts and fidelity, software/control systems and error correction, global on-premises deployments, and team growth.
