OpenSuperQ

An Open Superconducting Quantum Computer

OpenSuperQ aims at developing a full-stack quantum computing system of up to 100 qubits and to sustainably make it available at a central site for external users. This system will be applied to tasks of quantum simulation in quantum chemistry which serve as a high-level benchmark, and to problems related to optimization and machine learning. The core of the system will be a processor of superconducting qubits of the planar transmon type, with a square 2D layout and nearest-neighbour connectivity. The processor will be packaged with a control chip and integrated in a custom-made cryogenic system. This quantum computing system will be equipped with integrated control soft- and hardware ready for applications. The computer will be among the leading platforms in the world, and the first of its kind in Europe.

A distinguishing and globally unique feature of OpenSuperQ is its open approach ready to serve a large community of users of the system as well as of underlying technologies. The OpenSuperQ consortium works in a collaborative way with broad distribution of tasks and brings together theoretical and experimental teams, a central site including a high-performance computing center, and technology companies. It is supported by an advisory board, a basic science group, and a user board. This broad approach will lead to near-term exploitation, multi-level communication and will develop interfaces and standards made available to the quantum technology community at large.

FZJ has both theoretical and experimental tasks in OpenSuperQ, in theoretical device and small system modeling, in contributing to system software, and in developing application software. Building on its long experience in detailed quantum modeling of transmon devices, and of circuit QED structures, FZJ will contribute research on theoretical projects directly related to device experiments. Its major role in the consortium is however in establishing and coordinating the central site of OpenSuperQ. This will involve both the development of a central laboratory in Jülich for assembly of best-practice hardware to be used by all experimental groups in the consortium; it will also develop system-level software for the effective implementation of quantum algorithms on the central-site machine.
