What Atom Computing does

Atom Computing is a privately held U.S. quantum computing company founded in 2018 by Dr. Ben Bloom and headquartered in Berkeley, California, that builds gate-based universal quantum computers using arrays of optically trapped neutral atoms as qubits. Its qubits are encoded in the nuclear spin of Ytterbium-171 atoms, which the company selected because the closed outer electron shell provides insensitivity to environmental perturbations, enabling world-record coherence times exceeding 40 seconds and operation at room temperature without cryogenic cooling. Atom's flagship commercial system is the AC1000, which delivers more than 1,200 physical qubits with all-to-all connectivity, mid-circuit measurement with qubit reset and reuse, and real-time conditional branching — capabilities the company uses to demonstrate logical-qubit operations and, in June 2026, the first complete quantum error correction using a toric code on neutral atoms. The company is co-developing its next-generation Magne system with Microsoft, targeting a 50-logical-qubit fault-tolerant baseline.

The company makes money primarily through on-premises hardware sales of the AC1000 system to enterprise, government, and research customers (first commercial sale completed in 2025 to the QuNorth Nordic quantum initiative funded by EIFO and the Novo Nordisk Foundation in Denmark), supplemented by professional services and technical support, and by U.S. federal program revenue under DARPA's US2QC and Quantum Benchmarking Initiative, DOE National Quantum Information Science Centers, and a $100M Letter of Intent from the U.S. Department of Commerce under the CHIPS and Science Act. Atom operates a quote-based enterprise field-sales motion, supported by strategic integrations with Microsoft (QDK programming stack and Magne co-development), NVIDIA (NVQLink GPU-quantum interconnect), Cisco (quantum networking), and Nu Quantum (photonic networking). As of mid-2026, the company had raised more than $300 million in cumulative funding, employed approximately 130 people (predominantly in Boulder, Colorado), and operated offices in Berkeley, Boulder, Austin, and Denmark.

Revenue model

1. On-premises quantum hardware sales: Atom Computing sells its flagship AC1000 system (1,200+ qubits) for on-premises deployment to enterprise, government, and research customers. First commercial sale completed in 2025 to QuNorth, a Nordic quantum initiative funded by EIFO and Novo Nordisk Foundation. Each system has a footprint of approximately 600 sq ft / 56 m² with moderate power requirements and can be integrated into existing office buildings.
2. Technical support and partnership services: Atom Computing provides nearby and in-person technical support for on-premises AC1000 installations and acts as a supporting partner to help customers leverage Atom's expertise across their quantum ecosystems, including industry application exploration and academic research enablement.
3. Government and CHIPS Act funded contracts: Revenue derived from federal programs including DARPA US2QC and Quantum Benchmarking Initiative (Stage B), DOE National Quantum Information Science Centers (Quantum Science Center, Quantum Systems Accelerator), and a $100 million Letter of Intent with the U.S. Department of Commerce under the CHIPS and Science Act.

Core offering

Atom Computing builds and sells gate-based quantum computing systems that use arrays of optically-trapped neutral atoms (Ytterbium-171 nuclear-spin qubits) as the fundamental computational element. Its flagship AC1000 system delivers over 1,200 fully-connected physical qubits for on-premises deployment to enterprise, government, and research customers, accompanied by an OpenQASM/QIR software stack, a 20-qubit emulator, and technical support services. Atom also co-develops next-generation fault-tolerant systems such as Magne with Microsoft.

Product overview

Atom Computing offers a portfolio of neutral-atom quantum computing products centered on the AC1000, its flagship universal gate-based quantum computing system with over 1,200 physical qubits based on optically-trapped Ytterbium-171 atoms. The product architecture is a unified hardware-plus-software platform combining the AC1000 hardware with its software stack (OpenQASM/QIR APIs, real-time conditional branching) and a 20-qubit emulator, deployed via the On-Premises QuantumInsight model for enterprise, academic, and government customers. The next-generation Magne quantum computer is being co-developed with Microsoft targeting a 50-logical-qubit fault-tolerant system, while the Phoenix 100-qubit system served as the company's first-generation prototype and has been superseded by the AC1000.

Broad incumbents

• Google Quantum AI: Google's Quantum AI lab pioneered superconducting quantum computing and demonstrated the first below-threshold quantum error correction with surface codes (the only other company besides Atom to demonstrate deep QEC). Broad incumbent competing for talent, government grants, and enterprise customers. Atom's toric-code milestone is explicitly positioned against Google's track record.
• IonQ: IonQ is a publicly traded full-stack quantum computing company using trapped-ion technology. It serves enterprise customers via cloud (AWS, Azure, GCP) and direct channels, competing with Atom Computing for enterprise quantum compute spend but on a different modality and distribution model.
• Rigetti Computing: Rigetti is a publicly traded superconducting quantum computing company offering quantum systems via cloud and on-premises. While smaller and more focused, it competes with Atom Computing for government contracts (DARPA, DOE) and for early enterprise pilot customers.
• Quantinuum: Quantinuum (Honeywell/Cambridge Quantum merger) is a leading trapped-ion quantum computing platform serving enterprise, government, and research customers. Broad incumbent pursuing fault-tolerant roadmaps that overlap with Atom Computing's Magne-style logical-qubit milestones.
• PsiQuantum: PsiQuantum is pursuing fault-tolerant quantum computing using a photonic modality. It has raised >$900M and is targeting utility-scale systems. Comparable to Atom as a deep-tech, capital-intensive hardware peer pursuing large-scale fault-tolerant roadmaps with similar customer profile (national programs, hyperscalers).
• IBM Quantum: IBM Quantum operates one of the largest superconducting quantum computing fleets globally, distributed primarily via the cloud. Broad incumbent pursuing fault-tolerant roadmaps (e.g., IBM Quantum Heron, Condor) that compete with Atom Computing for enterprise R&D and government funding.

Direct peers

• QuEra Computing: QuEra builds gate-based quantum computers using arrays of neutral atoms (rubidium and ytterbium). It is the closest direct competitor to Atom Computing in modality, customer base (research, government, enterprise), and go-to-market (on-premises + cloud-access).
• Pasqal: Pasqal develops neutral-atom quantum processors using arrays of Rydberg-atoms and has raised significant capital. Direct competitor to Atom Computing in the neutral-atom modality and in serving European enterprise and government customers (e.g., through the EuroHPC/JUPITER program).
• Infleqtion (formerly ColdQuanta): Infleqtion builds quantum computing and sensing platforms based on cold neutral atoms. It is a direct peer in the neutral-atom modality, competing for U.S. government and commercial customers and pursuing on-premises and cloud-access delivery models.

Emerging players

• Xanadu: Xanadu builds photonic quantum computing platforms and is pursuing both utility-scale hardware and software (PennyLane). Emerging player competing for fault-tolerant roadmap milestones and for quantum software/algorithm partnerships analogous to Atom's Phasecraft and Microsoft collaborations.
