# Atom Computing

> Atom Computing builds gate-based quantum computers from neutral ytterbium atoms held and rearranged by lasers. Its AC1000 platform combines more than 1,200 physical qubits, all-to-all connectivity, long coherence, mid-circuit measurement, and qubit reset and reuse. The business sells on-premises systems and technical support to governments, research institutions, and enterprises, with Microsoft, QuNorth, DARPA, NVIDIA, Cisco, NREL, Nu Quantum, and Phasecraft among its notable customers or collaborators.
