A quantum computing startup you’ve never heard of just raised more money in a single round than most crypto protocols see in a lifetime. Oratomic, founded by Caltech researcher Dolev Bluvstein, emerged from stealth with a $300 million Series A and a plan to build a utility-scale quantum computer packing 10,000 to 20,000 qubits by 2030.

The round was co-led by ARCH Venture Partners, Spark Capital, and Khosla Ventures. Bezos Expeditions, Index Ventures, and General Catalyst also participated, pushing the post-money valuation to roughly $1.5 billion.

What Oratomic is actually building

The Pasadena-based company is developing fault-tolerant quantum computing systems that use reconfigurable neutral-atom qubits. Instead of the fragile, error-prone quantum bits that define today’s machines, Oratomic is working with atoms suspended by laser beams (called optical tweezers) and arranged using topological error correction methods.

The team behind this effort draws from Caltech, Harvard, Berkeley, Amazon, and Google. Bluvstein’s academic work, particularly a paper published in March 2026, forms the intellectual backbone of the company. That research suggested something that sent ripples through the cryptography world: Shor’s algorithm, the quantum algorithm capable of breaking widely used encryption, could potentially run on far fewer qubits than previously assumed.
