EuRyQa - European infrastructure for Rydberg Quantum Computing
A scalable route to quantum computers based on Rydberg atoms
Ultracold trapped atoms are among the most promising physical platforms for quantum computing. Following the demonstration of systems containing more than 200 qubits with strong and controllable interactions mediated by their highly excited Rydberg states, they can provide a clear path to further scalability. The EU-funded EuRyQa project plans to develop the next generation of fully programmable and scalable quantum computing systems based on ultracold Rydberg atoms. It will bring together four complementary European Rydberg platforms with 100-1 000 qubits and establish the first benchmarks and standards for the technology. To achieve its aims, EuRyQa will unite partners from academia and a European start-up at the forefront of ultracold-atom-based quantum technology with industrial partners providing complementary expertise on quantum hardware, classical electronics, firmware, and software.
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.
