Company intelligence
As of June 16, 2026, Atom Computing has raised at least $100M in equity across 1 sourced funding round.
Atom Computing builds neutral-atom quantum computers aimed at fault-tolerant, commercial-scale quantum computing.
Atom Computing builds quantum computers from arrays of optically trapped neutral atoms.[1] Ben Bloom founded the company in January 2018.[2] Its website lists an address in Berkeley, California.[2] The company has built systems with more than 1,200 qubits.[1] In 2023 it became the first quantum company to pass 1,000 qubits in a universal gate-based system.[1] Atom Computing is in Stage B of DARPA's Quantum Benchmarking Initiative and is installing a commercial quantum computer with logical qubits in partnership with Microsoft.[1] In 2025 it sold its first on-premises quantum computer to QuNorth, a Nordic initiative funded by EIFO and the Novo Nordisk Foundation.[1] Third Point Ventures had backed the company since its Series B.[1] The company said the money will fund larger, higher-fidelity systems, error-correction software, global deployments and team growth.[1]
Atom Computing is a Berkeley, California quantum computing company installing the first commercial quantum computer with logical qubits alongside Microsoft.
Atom Computing is a U.S. company building quantum computers using arrays of optically trapped neutral atoms, according to TechCrunch's roundup of companies racing to build quantum chips. The company says it was the first to build nuclear-spin qubits out of an alkaline earth element, per the PR Newswire release announcing its Series A funding.[1],[2]
Atom Computing's first-generation system, Phoenix, traps 100 atoms in a vacuum chamber with optical tweezers and uses lasers to rearrange and manipulate their quantum states, the company said when it unveiled Phoenix in July 2021. In 2023, Atom Computing became the first quantum company to surpass the 1,000-qubit threshold for a universal gate-based system, according to the company's June 2026 funding announcement.[2],[3]
Atom Computing secured more than $15 million in Series A funding from Venrock, Innovation Endeavors and Prelude Ventures, plus three National Science Foundation grants, the company said in its July 2021 Phoenix launch announcement. A Form D that Atom Computing Inc. filed with the SEC on July 20, 2021 reports total securities sold of $15,999,999.[2],[4]
Atom Computing closed a $60 million Series B round in January 2022, led by Third Point Ventures with participation from Prime Movers Lab and existing investors Innovation Endeavors, Venrock and Prelude Ventures, according to the company's announcement. A related Form D that Atom Computing Inc. filed on January 13, 2022 lists a total offering amount of $61,849,929 and total amount sold of $58,849,929.[5],[6]
Atom Computing raised more than $300 million in total new funding announced in mid-2026, combining a $100 million Series C round led by Third Point Ventures with participation from DCVC and Cisco Investments, and a signed Letter of Intent with the U.S. Department of Commerce for another $100 million in CHIPS research and development funding, the company said in its June 2026 announcement. Commerce Secretary Howard Lutnick is quoted in the May 2026 release announcing the Letter of Intent.[3],[7]

Atom Computing announced its first-generation quantum computing system, Phoenix, in July 2021, at the same time it appointed Rob Hays as CEO, President and a board member following the close of its Series A round, the company's release says. Co-founder Ben Bloom, who held the title of chief technology officer at that time, stayed on to lead the engineering team.[2]
Atom Computing was still based in Berkeley, California as of its January 2022 Series B announcement, which described the company as the creator of the first quantum computer made of nuclear-spin qubits from optically trapped neutral atoms. By the company's June 2026 funding release, Ben Bloom is quoted as CEO and Founder of Atom Computing; the sources opened for this profile do not explain the change from Rob Hays's 2021 appointment as CEO.[5],[3]
Atom Computing's SEC filings list its address as 918 Parker Street, Suite A13, Berkeley, CA, in both its 2021 and 2022 Form D filings, with the company incorporated in Delaware.[8],[9]
Ben Bloom, Ph.D., co-founded Atom Computing and led its engineering team as CTO starting in 2021; by the company's June 2026 release, Bloom is identified as Atom Computing's CEO and Founder. Curtis McKee, Partner at Third Point Ventures, joined Atom Computing's board of directors when the firm led the company's Series B round in January 2022.[2],[3],[5]
Atom Computing is engaged in strategic collaborations with Cisco and NVIDIA, and Cisco Investments took part in the company's $100 million Series C round, according to Atom Computing's June 2026 funding release. The company is also performing on Stage B of DARPA's Quantum Benchmarking Initiative, which explores paths to utility-scale quantum systems.[3]
Atom Computing signed a Letter of Intent with the U.S. Department of Commerce in May 2026 for $100 million in CHIPS Research and Development funding, with Commerce Secretary Howard Lutnick quoted in the announcement as saying the investment would build on the company's domestic manufacturing and create high-paying jobs.[7]
Atom Computing also competes with Big Tech's own quantum chip programs. TechCrunch's survey describes Google's Willow chip, announced in December 2024, and Amazon's Ocelot chip, introduced via AWS in early 2025 in partnership with the California Institute of Technology; it notes AWS also offers its Braket quantum computing service in partnership with D-Wave, IonQ and Rigetti.[1]
