Atom Computing
Neutral-atom · Founded 2018 · Berkeley, CA / Boulder, CO
Neutral-atom (strontium) systems with focus on high-qubit-count scaling. Phoenix: 1,180 qubits announced late 2023, first system to publicly exceed 1,000 qubits. Slower on gate-fidelity milestones than trapped-ion competitors; faster on raw qubit count.

Our verdict
Atom Computing has delivered every dated qubit-count milestone. Their advantage is the natural scalability of optical-tweezer arrays — adding atoms is mostly an optics-and-laser problem, not a fab problem. Open question: gate-fidelity scaling to match trapped-ion. The Microsoft collaboration's logical-qubit demonstration is a real and important credibility signal.
