About Atom Computing

Atom Computing is a quantum computing company headquartered in Berkeley, California, with a commercial operations facility in Boulder, Colorado. Founded in 2018 by Ben Bloom and Jonathan King, it builds gate-based quantum computers using arrays of optically trapped neutral atoms, and in 2023 announced a second-generation system with over 1,000 qubits.

Atom Computing partnered with Microsoft in late 2024 to demonstrate logical qubits by combining Microsoft's quantum error correction with Atom's hardware, and the Colorado Technology Association named it Emerging Tech Company of the Year.
