Oratomic, Inc Oratomic is building utility-scale, fault-tolerant quantum computers using ultra-efficient error correction, light, and atoms. Its machines are based on reconfigurable arrays of neutral atoms, and the company says its architecture could reach cryptographically relevant computation with about 10,000 atomic qubits. Oratomic launched in March 2026 led by CEO Dolev Bluvstein and co-founder Manuel Endres, with an initial team from Caltech, Berkeley, Harvard, Amazon and Google that includes John Preskill. In October 2026 it announced $775M in total funding, including a $475M Series B led by ARCH Venture Partners, Spark Capital, Khosla Ventures, Index Ventures, General Catalyst and Bezos Expeditions.
