About
Oratomic is a Pasadena, California quantum computing company building fault-tolerant, utility-scale quantum computers using reconfigurable neutral-atom qubits 123. The company was founded in late March 2026 by CEO Dolev Bluvstein and Manuel Endres, in collaboration with scientists at the California Institute of Technology 12. Oratomic’s approach explicitly skips noisy intermediate-scale quantum (NISQ) systems in favor of going directly to fault-tolerant architectures, using neutral atoms trapped in optical tweezer arrays as qubits 23. The team includes prominent quantum researchers including Caltech theoretical physicist John Preskill and researchers from UC Berkeley, Harvard, Amazon, and Google 1.
On 2026-07-07 Oratomic announced a $300M Series A co-led by ARCH Venture Partners, Spark Capital, and Khosla Ventures 1234567. Vinod Khosla, founder of Khosla Ventures, said the firm “made the largest initial investment yet, as we did in OpenAI, into @TeamOratomic after we looked at a dozen Quantum starts in a decade” 1. Oratomic will use the capital to fund quantum hardware fabrication, algorithmic R&D on fault-tolerant logical qubits, and hiring across physics and hardware engineering 15.
