Atom Computing

Atom Computing is a Berkeley-based quantum computing company that develops quantum computers using optically trapped neutral atoms — a different physical approach from superconducting qubits (IBM, Google) and trapped ions (IonQ). Neutral atom systems use lasers to individually manipulate thousands of atoms simultaneously, offering a potential path to much larger qubit counts than competing technologies. Atom Computing's Phoenix system was the first neutral atom computer to demonstrate 1,000+ qubit operation, a milestone in scaling quantum hardware. The neutral atom approach enables all-to-all qubit connectivity — any qubit can interact with any other — unlike superconducting systems where qubits can only interact with immediate neighbors, simplifying algorithm design. The company was founded in 2018 and raised over $60M from investors including Innovation Endeavors, Prelude Ventures, and Venrock. Atom Computing announced a partnership with Microsoft to integrate its neutral atom hardware with Azure Quantum. It competes with QuEra Computing and Pasqal in the neutral atom quantum computing market.
