Atom Computing
Atom Computing is a Neutral-Atom Qubits company founded in 2018 and based in Boulder, United States. It has raised $175M in total funding, most recently a Series C in 2026.
Atom Computing develops neutral-atom quantum computers using optical tweezers to trap and manipulate individual atoms. Its AC1000 platform has more than 1,200 physical qubits and is sold for on-premises deployment as well as offered through Microsoft Azure Quantum. In June 2026, Atom closed a $100 million Series C and separately announced a non-binding $100 million U.S. Department of Commerce letter of intent.
Atom combines one of the highest physical-qubit counts in a gate-model commercial system with repeated toric-code error-correction experiments and a path to modular scale-out through its Nu Quantum partnership.
