European infrastructure for Rydberg Quantum Computing

EuRyQa aims at establishing Rydberg quantum processors as a leading platform for scalable quantum computing. Rydberg atoms have already provided proof-of-principle demonstrations of all the requirements for general purpose digital quantum computing and are today the only platform that has demonstrated more than 200 qubits with strong interactions and with a clear path to further scalability and eventually fault tolerant operation. To develop the next generation of fully programmable and scalable quantum computing systems based on Rydberg atoms and open them up for the European community now requires a coordinated interdisciplinary and intersectoral effort. For this, the EuRyQa consortium combines partners from academia and the private sector that are at the forefront of cold-atom technology with key industrial partners with complementary expertise on quantum hardware, classical electronics, firmware, and software. The project will bring together four Rydberg platforms with 100-1000 qubits, including three nationally funded platforms and one leading European start up, to provide a unique European solution to Rydberg-based quantum computers together with Europe-wide benchmarking and standardization of the technology. We will provide a common quantum computing stack for Rydberg atoms, a federated cloud service, solutions to concrete computational problems leading to a quantum advantage, and key technology and a blueprint for fault-tolerant quantum computing with Rydberg qubits.
