Atom Computing funding rounds
| Date | Stage | Investors | Raised | Valuation | Deal Summary |
|---|---|---|---|---|---|
| Jun 2026 | Series C | Third Point Ventures (lead); Cisco Investments; DCVC | $100M | - | Atom Computing raised over $300 million in total funding on June 16, 2026, highlighted by a $100 million Series C equity round led by Third Point Ventures with participation from DCVC and Cisco Investments, alongside a $100 million Letter of Intent from the U.S. Department of Commerce under the CHIPS and Science Act. The Series C-1 round specifically valued the company at $714.4 million post-money as of June 2026. This capital infusion accelerates Atom's roadmap to deploy fault-tolerant, neutral-atom quantum computers for commercial availability. The strategic involvement of Cisco Investments and DCVC underscores strong investor confidence in Atom's potential to lead the emerging quantum computing sector. Atom Computing, headquartered in Boulder, Colorado, develops neutral-atom quantum technology and partners with major industry players including Microsoft (which uses Atom's qubits for its quantum systems), Nvidia, and Cisco Systems. The company is racing to build the world's first fault-tolerant, commercially viable quantum computer, leveraging its unique neutral-atom architecture to achieve practical, large-scale quantum computing capabilities. The funding aligns with broader industry trends toward networked and distributed quantum computing, complementing Cisco's initiatives in advanced computing and networking, including projects like the Secure AI Factory and new high-capacity Nexus switches. The $100 million federal LOI represents government equity investment in exchange for a minority, non-controlling stake, further strengthening Atom's position in the quantum computing sector. Third Point Ventures, which previously invested in Atom's Series B, led this round, signaling continued confidence from a key backer. DCVC, an early supporter, and Cisco Investments, a strategic participant, joined alongside other unnamed investors. The combined capital brings Atom's total funding to over $300 million, marking a pivotal moment reinforcing its trajectory toward practical quantum computing powered by neutral atoms. Atom Computing operates as a quantum computing startup focused on developing and deploying fault-tolerant neutral-atom quantum computers. The company's technology enables utility-scale quantum computing through partnerships with Nu Quantum and strategic collaborations with Cisco to advance scalable, networked, and distributed quantum computing systems. Founded by Ben Bloom, Atom has raised significant capital across multiple rounds, with its latest Series C round representing a major milestone in its growth trajectory. The company's neutral-atom qubits and related technologies are being utilized by Microsoft for its own quantum systems, demonstrating the practical applicability of Atom's innovations in the quantum computing field. |

| Jan 2022 | Series B | Third Point Ventures (lead); Prime Movers Lab; Innovation Endeavors; Prelude Ventures; Venrock; Fernando Pontaza; Invariantes Fund | $60M | - | Atom Computing, a Berkeley-based quantum computing company founded in 2018 by Benjamin Bloom Ph.D. and Jonathan King Ph.D., develops scalable quantum computers using nuclear-spin qubits from optically-trapped neutral atoms. Atom Computing focuses on enabling breakthroughs in materials science, cryptography, and optimization through practical quantum systems accessible to researchers and businesses. The company announced the closure of a $60 million Series B funding round on January 20, 2022, led by Third Point Ventures, with participation from Prime Movers Lab (noted as Primer Movers Lab in some reports), Innovation Endeavors, Venrock, Prelude Ventures, and other insiders. This followed their achievement of a 100-qubit quantum computing system with world-record 40-second coherence times. The funds were intended to build second-generation quantum computing systems. The company has collaborated with U.S. government entities like the Department of Defense, Department of Energy, and National Science Foundation. |
| Jul 2021 | Series A | Innovation Endeavors (lead); Prelude Ventures (lead); Fifty Years; Venrock; Cantos | $15M | - | Atom Computing is a quantum computing startup developing nuclear-spin qubits using an alkaline earth element to build scalable quantum systems. The company unveiled its first-generation quantum computing system, Phoenix, a 100-atom system demonstrating unprecedented stability, on July 21, 2021. Phoenix traps 100 atoms in a vacuum chamber with optical tweezers and manipulates their quantum states with lasers. Atom Computing closed a $15 million Series A funding round on July 21, 2021, with investments from Venrock, Innovation Endeavors, and Prelude Ventures. The funding supports growth, including assembling a team of quantum physicists and design engineers, and developing scalable quantum platforms compatible with error correction. The company also received three grants from the National Science Foundation. Rob Hays, a computing industry veteran and former vice president at Lenovo, was appointed CEO, President, and board member, while co-founder Ben Bloom, Ph.D., continues leading engineering efforts. The company plans to recruit talent, improve Phoenix, build second-generation systems, and allow pilot customers to run algorithms for feedback. |
