Ultracold trapped atoms have recently emerged as one of the most promising physical platforms for digital quantum computing, having already demonstrated systems with more than 200 qubits (the computational unit of a quantum computer) with strong interactions mediated by their highly excited Rydberg states and a clear path to further scalability to thousands of qubits. To develop the next generation of fully programmable and scalable quantum computing systems based on ultracold Rydberg atoms, EuRyQa will bring together four complementary European Rydberg platforms. In this way, the consortium aims to provide a unique European solution for Rydberg-based quantum computing, together with the first pan-European benchmarking and standardisation of the technology.

To achieve the project’s aims, EuRyQa unites partners from academia at the forefront of ultracold-atom-based quantum technology with industrial partners providing complementary expertise on quantum hardware, classical electronics, firmware, and software. EuRyQa is coordinated by the University of Strasbourg (France) and other partners include the SMEs PASQAL (France) and Quantum Machines Technologies (Israel), the University of Stuttgart, the spin-off Qruise GmbH from the Research Centre Jülich, and the consultancy EURICE GmbH (Germany), the University of Amsterdam and the Technical University of Eindhoven (the Netherlands), the research center FORTH (Greece), Associacao Portuguese Quantum Institute (Portugal), and Università degli Studi di Padova (Italy).
