Neutral-Atom Platform Technologies

Among the outcomes of the call there are:

• Fully programmable, industry-ready quantum simulators based on up to 10 000 neutral atoms in a scalable architecture, accessible through cloud platforms and interoperable with high-performance computing (HPC) environments.
• Fully programmable neutral-atom quantum computing platforms supporting both analogue and gate-based quantum computing with 1 000 physical qubits, together with a credible roadmap towards 10 000 physical qubits.
• Long coherence times (of the order of hundreds of interaction times) and operation infidelities below 1%.
• Demonstration of quantum simulation and/or computing beyond classical computability through validated benchmarking against state-of-the-art classical methods.
• Demonstration of at least two real-world applications in science or industry (e.g. energy, health, materials science, chemistry or optimisation).
• A complete software stack, including quantum control software, verification tools, algorithm implementation frameworks and user-friendly programming interfaces.
• Demonstration of the full quantum computing stack, including quantum processors, control electronics and verification tools.
• Enhanced scalability, stability and usability of neutral-atom quantum simulation and computing platforms.
• Strengthened European industrial and technological capabilities across the neutral-atom quantum computing value chain.

Proposals should advance the maturity, scalability and usability of neutral-atom quantum processors for practical quantum simulation and computing applications.

They must address at least two of the technical challenges identified in the SRIA 2030 for neutral-atom platforms, such as stable atom control during multi-qubit operations, Quantum Non-Demolition (QND) measurement, or high-fidelity universal gate operations, with the objective of enabling scalable, fault-tolerant quantum simulation and computing.

Activities from the selected proposal should include, among others:

• Development and deployment of scalable neutral-atom quantum processors with individually addressable atoms supporting analogue quantum simulation, hybrid analogue-digital approaches and gate-based quantum computing.
• Demonstration of at least two real-world scientific or industrial use cases addressing problems beyond the reach of classical computing, including appropriate benchmarking and verification methodologies.
• Development and integration of a complete software and control stack, including quantum control systems, electronic control components, user programming interfaces, classical simulation tools and robust operational protocols.
• Provision of cloud-based access supporting hybrid quantum-HPC workflows and broad accessibility for researchers and industrial users, including non-experts where appropriate.
• Coordination, training, documentation and user engagement activities to accelerate adoption and strengthen the European quantum ecosystem.
