About
Atom Computing is a US neutral-atom quantum computing company based in Boulder, Colorado and Berkeley, California. In November 2024 it demonstrated 24 logical qubits entangled using Microsoft's Bacon-Shor error correction, the largest logical qubit entanglement on record at the time. The same demonstration also featured 28 logical qubits running the Bernstein-Vazirani algorithm with accuracy superior to unencoded physical qubits, the first demonstration of active QEC advantage on a commercial neutral-atom platform. The company operates a reconfigurable atom array of more than 1,200 physical qubits and partners with Microsoft Azure Quantum, integrating its system into the Azure Quantum Elements platform for chemistry and materials research. Atom Computing was recognized as Fast Company's number 10 Most Innovative Company in 2025. In 2025 and 2026, Atom Computing partnered with Microsoft and QuNorth on Magne, a next-generation fault-tolerant quantum computer targeting late 2026, aiming for 50 logical qubits and more than 1,200 physical qubits. Positioned as the world's first commercially available Level 2 quantum computer, Magne combines Atom Computing's neutral atom array hardware with Microsoft's quantum error correction software stack. In January 2026, QuNorth in Denmark became the first customer to receive and commercially launch the Magne system, funded by 80M DKK from EIFO and the Novo Nordisk Foundation, making it the first commercially deployed Level 2 quantum computer outside the US. In March 2026, Atom Computing integrated NVIDIA NVQLink for tighter GPU-QPU coupling in hybrid quantum-classical workflows. On 21 May 2026, Atom Computing signed a non-binding letter of intent with the US Department of Commerce CHIPS R&D Office for up to $100 million in federal incentives to scale neutral-atom hardware toward tens of thousands of addressable qubits. The Department will take a minority equity stake on completion of a definitive agreement. The award is part of
