About

Atom Computing builds highly scalable, gate-based quantum computers using arrays of optically-trapped neutral atoms, designed to deliver unprecedented computational breakthroughs. The company AC1000 system features 1,200+ fully-connected qubits, enabling entry into the logical qubit era with error correction capabilities. The neutral atom approach offers advantages in scalability, long coherence times, optimized connectivity, and fast operations, positioning it as what the company believes is the easiest and fastest path to quantum computing at scale. Atom Computing has announced a groundbreaking collaboration with Microsoft to build quantum supercomputers and partnered with Nu Quantum to unlock utility-scale quantum computing. The company focuses on developing large-scale quantum computers for on-premises deployment with features including mid-circuit measurement, and offers tools for quantum algorithm developers to tackle commercially valuable applications. Founded in 2018 and headquartered in Berkeley, California, Atom Computing has raised over $300 million in Series C funding from investors including Khosla Ventures, Venrock, Innovation Endeavors, Prelude Ventures, DCVC, Cisco Investments, Prime Movers Lab, and Third Point Ventures.
