EuRyQa publishes white paper on the future of neutral atom quantum computing in Europe

The EuRyQa consortium has published a white paper setting out the technical state of the art and the strategic steps needed to achieve large-scale fault-tolerant quantum computing (FTQC) with neutral atoms. The paper reflects contributions from all eleven consortium partners and is intended to inform the next EU programme for research and innovation as well as the forthcoming Quantum Act.

The white paper documents major advances made during the project, including new gate protocols that have pushed two-qubit gate fidelities above 99.7%, clearing a key threshold for practical error correction, alongside progress on quantum error-correcting codes, logical qubit demonstrations, and integrated classical control systems. Neutral-atom arrays have now exceeded 6,000 programmable qubits, and the paper argues this platform is currently among the most promising for scaling to the million-qubit systems that full fault tolerance will require.

To sustain this momentum, EuRyQa calls for a large-scale, coordinated European initiative combining public and private investment, mission-oriented research programmes, and joint industry-academia competence centres.

The consortium also highlights the need to build a robust European supply chain for the specialised lasers, optical components, and control electronics that future quantum processors will depend on.
