Building Europe's Neutral-Atom Quantum Computers
EuRyQa is a European research programme developing neutral atom-based quantum computers, covering the full stack from hardware to software. Researchers across multiple institutions share progress on high fidelity qubit gates, quantum error correction, and middleware development, with the goal of building fault tolerant quantum computers that are already partially accessible to users today.

Three Years That Shaped European Quantum Computing
EuRyQa is a European research network that set out to build a new infrastructure for quantum computing based on neutral atom technology. Over the course of the project, researchers and private sector partners collaborated to advance gate fidelities, quantum error correction, and fault tolerant computing, establishing neutral atoms as one of the leading platforms for scalable quantum computing. The project also gave rise to new spinout companies and platforms now accessible to the public, leaving behind a model of academic and industry collaboration that aims to shape the future of quantum computing in Europe.
Interview with Antoine Browaeys
In this interview, Antoine Browaeys reflects on how rapidly neutral atom quantum computing has advanced, with fidelities now rivalling other leading platforms and unique advantages for fault tolerant computation. Unlike circuit-based systems, neutral atoms allow any two qubits to be brought together and entangled directly, enabling transversal gates that make fault tolerance more achievable by design. Combined with the ability to trap thousands of atoms, the platform offers a promising path toward large scale logical qubits. Browaeys also shares his perspective on the importance of this moment for the European community, highlighting the need to strengthen collaboration across a growing number of groups and celebrating the enthusiasm of the many young researchers who are driving the field forward.

Interview with Johannes Zeiher
In this interview, Johannes Zeiher reflects on the remarkable progress of neutral atom quantum computing, a field that has transformed from uncertain beginnings into one of the most promising platforms for fault tolerant computation. He highlights the intrinsic scalability of neutral atoms as a key advantage, while acknowledging that realising that potential requires continued improvements in underlying technologies such as lasers and optical switches. Zeiher also emphasises the importance of scientific exchange at conferences like this one, where the community comes together to share ideas and drive progress. He expresses enthusiasm for the growing involvement of startups in the field and hopes the conference will help sustain a strong community spirit as the work toward fault tolerant quantum computing continues.
Interview with Guido Pupillo
In this interview, Guido Pupillo discusses the motivations behind bringing the European neutral atom quantum computing community together, with the goal of making the conference an annual meeting point for researchers, experts, and companies in the field. He outlines why neutral atoms stand out as a platform, pointing to their scalability, flexibility, and the precision with which they can be manipulated. Pupillo also reflects on the broader transition the field is undergoing, moving from noisy imperfect qubits toward fault tolerant quantum computing. He shares details about an upcoming white paper that proposes a new set of criteria for the field, covering scalable high-quality qubits, quantum error correction, fault tolerant logic gates, and integrated classical co-processing as the key milestones the community must achieve on the path to practical quantum computers.

Interview with Simone Montangero
In this interview, Simone Montangero reflects on the rapid and often unexpected progress of neutral atom quantum computing, highlighting recent demonstrations of large-scale quantum error correction as a major step toward fault tolerant systems. He expresses confidence that neutral atoms have emerged as one of the leading platforms in the broader quest for useful quantum computers and underlines the importance of European participation in both experimental and theoretical developments. Montangero also speaks to the significance of the conference as a gathering point for the community beyond the EuRyQa project, with plans already in place for a follow up event in 2027. He closes by identifying the software stack as the most pressing challenge ahead, as the field moves from handling tens of qubits to manipulating hundreds or thousands, requiring mature, full stack software solutions developed in close collaboration with the classical computing community.
