Periodic Reporting for period 1 - OpenSuperQPlus100 (Open Superconducting Quantum Computers (OpenSuperQPlus))

Reporting period: 2023-03-01 to 2024-08-31

Summary of the context and overall objectives of the project

The OpenSuperQPlus project is part of the European flagship programme on quantum technologies. It aims at developing disruptive quantum computing systems based on superconducting integrated circuits as well as develop the necessary technological ecosystem around them. The integrated, all-European approach aims at creating technological sovereignty as well as a prominent position for Europe in the global quantum computing ecosystem. The project is approaching this goal by leveraging a team of partners from European universities, RTOs and enterprises. OpenSuperQplus will deliver three demonstrators for different user communities – a scaled-up system with 100 qubits pushing the envelope for large-scale applications, a system with pulse-level access for theoretical and software development, and an alterantive qubit demonstrator that allows to test new qubit designs in an integrated system. The ecosystem of components and modules contain cryogenics, wiring, quantum processor, quantum-limited amplifiers, firmware and compilers. The resulting systems will be tested using a suite of real-world use cases.
The project contains an evaluation of the ethics of quantum computer access and it bundles the partner's activities in the area of education.

Work performed from the beginning of the project to the end of the period covered by the report and main results achieved so far

In its first 18 months, OpenSuperQplus has consolidated its team of 28 partners, which brings together many partners that also play prominent roles in their respective ecosystems. It has advanced its quantum processing units along the critical path in size and quality but also outlined one likely alternative to this critical path. Most notably, the consortium is ready to develop three-dimensionally integrated multi-chip modules. It has developed wiring, cooling and readout solutions for that can be scaled to 100 qubits and beyond. It has upgraded the architecture of electronics for control systems to the capability of 100 qubits. The software stack needed to access these systems has passed its first evaluation and is now connected towards full HPC (high performance computing) integration. Its benchmarking and test suite has published a first prototype that is being continuously refined. Most notably, the three demonstrator sites have reached an intermediate-size system that will be released to the public soon, preparing for the full-scale system.

Progress beyond the state of the art and expected potential impact (including the socio-economic impact and the wider societal implications of the project so far)

OpenSuperQPlus is monitoring the key exploitable results and supporting commercialization activities. Partners have already published 26 open access papers and disseminated early results in various scientific conferences. The consortium is active in standardisation at JTC 21 of CEN/CENELEC and its related national committees. Various partners have attracted additional national funding and/or investment based on their work in OpenSuperQPlus.
