Oratomic raises $300 million to build fault-tolerant neutral-atom computers
Jul 7, 2026
On July 7, 2026, neutral-atom hardware startup Oratomic announced a $300 million Series A round, co-led by ARCH Venture Partners, Spark Capital and Khosla Ventures, to build fault-tolerant, utility-scale quantum computers from arrays of individually trapped atoms.
Why it matters
The round backs a team whose March 2026 study argued that useful fault-tolerant machines might need about 10,000 atoms rather than millions, a bet on reaching error-corrected computing with far less hardware.
