Atlantic Quantum is an MIT spinout founded in 2022 that developed next-generation superconducting quantum computers using fluxonium qubits, a promising alternative to transmon qubits that offers superior coherence properties and reduced sensitivity to charge noise. The company was founded by leading quantum computing researchers from MIT including Peter Gruter, Youngkyu Sung, and others who pioneered fluxonium qubit technology. Atlantic Quantum’s approach leveraged the unique properties of fluxonium qubits, which can achieve microsecond-scale coherence times and strong anharmonicity, potentially enabling more efficient quantum error correction and higher-fidelity quantum operations. In October 2025, Google Quantum AI acquired Atlantic Quantum to advance scalable quantum hardware development, integrating the company’s advanced fluxonium qubit technology into Google’s quantum computing roadmap. The acquisition represented a strategic move by Google to strengthen its quantum hardware capabilities by bringing cutting-edge academic research from MIT into commercial applications. Atlantic Quantum’s focus on advanced qubit technology positioned them to contribute significantly to Google’s pursuit of fault-tolerant quantum systems.
