Atom Computing, Inc.

Atom Computing, Inc. develops scalable quantum computers based on arrays of optically trapped neutral atoms. The company describes its systems as gate-based and aimed at large-scale, fault-tolerant quantum computing, with features including long coherence times, mid-circuit measurement, and fully connected qubits.

The company says it was founded in January 2018. Its website lists Berkeley, California as its address and presents the AC1000 as a current product, alongside a prior 100-qubit system called Phoenix. Atom Computing’s timeline notes milestones including trapping its first atom in 2019, creating nuclear spin qubits in 2020, unveiling Phoenix in 2021, and publishing coherence-time results in 2022.

The site also states that Atom Computing closed a $60 million Series B round in January 2022 to build second-generation commercial systems. Leadership pages identify Ben Bloom as CEO and founder and Jonathan King as chief scientist and co-founder, alongside other executives responsible for product, finance, and engineering.
