Quantum computing firm Atom Computing has secured new funding.. The company this week announced it has raised a total funding of more than $300 million to accelerate the development and deployment of its quantum computers.. – Atom Computing. The funding includes $100m Series C investment round and a signed Letter of Intent with the US Department of Commerce for $100m..
The Series C round was led by Third Point Ventures, with participation from DCVC, Cisco Investments, and others.. “Quantum computing is entering a new phase where technical breakthroughs are translating into real-world systems and global adoption, fueled by our neutral-atom technology,” said Dr.
Ben Bloom, CEO and founder of Atom Computing. “We have strong momentum, and we are accelerating the development of utility-scale quantum computers and expanding access to our technology for customers solving some of the world’s most complex computational challenges.”. Founded in 2018, Atom is developing an atomic array-based quantum computer, and is one of the first companies to develop a 100-qubit prototype of that approach.
The company operates a data center in Boulder, Colorado, that hosts several systems.. “Third Point Ventures has backed Atom Computing since their Series B, and leading this Series C reflects our deepening conviction in both the team and the technology,” said Curtis McKee, partner at Third Point Ventures.
“Neutral-atom quantum computing is one of the most credible paths to fault-tolerant systems at scale, and we believe commercial breakthroughs — in cybersecurity, defense, drug discovery, and financial modeling — are closer than the market appreciates. Atom Computing will be at the center of that moment.”.
Rather than the golden chandeliers and dilution fridges that require supercooling, Atom’s system uses optical tables and lasers for its quantum mechanics. Its AC1000 system offers 1,200+ physical qubits (though far fewer logical qubits, around 30).. The company has raised more than $190m across 12 funding rounds.
Previous investors include Alumni Ventures, BoxGroup, SV Angel, and the National Science Foundation.. “Atom Computing’s roadmap and execution towards a neutral atom fault-tolerant quantum computing is truly impressive. DCVC has been with the Atom team from the start, and we are delighted to double down!” said Dr.
Prineha Narang, DCVC operating partner.. Atom is working with Microsoft to deploy a large-scale quantum computer in Denmark, due live next year. It will be Atom’s first commercial on-premises deployment..
“Quantum computing is rapidly evolving from a research pursuit into a technology platform with real-world enterprise implications. As it matures, the industry will require scalable infrastructure, secure networking, and strong ecosystem collaboration to support real-world deployment,” added Aleem Rizvon, VP, Cisco Investment.
“We are excited to invest in Atom Computing as it establishes itself as a leader in neutral-atom quantum computing.”. More in Investment / M&A / Financing. 19 Feb 2026.
