Atom Computing ^Company

Atom Computing builds truly scalable quantum computers out of individual atoms.
The company's quantum computers use quantum mechanical properties of atoms to process information and solve problems beyond the reach of traditional computers, including drug design, computational chemistry, and more.
Atom Computing was founded in 2018 and based in Berkeley, California.

Atom Computing is a U.S.-based quantum computing company (founded 2018, headquartered in Berkeley, California, USA) specializing in neutral-atom quantum computers using optically trapped arrays of neutral atoms (strontium-87) for scalable, high-coherence qubits. It has achieved world-record coherence times and qubit counts (e.g., 1,225-qubit system announced 2023, with plans for larger fault-tolerant systems). Systems are available via cloud (e.g., partnerships with Microsoft Azure Quantum for commercial access in 2025). Focus areas include biotech (quantum simulations for molecular dynamics and drug discovery), cybersecurity (quantum-accelerated optimization for post-quantum crypto analysis), and communications (quantum network simulation, error-corrected quantum repeaters). Atom Computing partners with Microsoft, DARPA (IMPACCT program for utility-scale quantum), and national labs. Total funding raised: ~$272M+ across rounds (latest Series C-1 $181.69M in Feb 2026, Series B $69.06M in Jun 2024 and earlier $60M Series B in Jan 2022). Private company; valuation ~$722M+ post-2026 round. Data from company website (atom-computing.com), press releases, PitchBook, Crunchbase, Tracxn, TechCrunch, Forbes (as of Feb 2026).
