Forschungszentrum Jülich - Jülich Supercomputing Centre (JSC)

The Jülich Supercomputing Centre (JSC) at the Forschungszentrum Jülich (FZJ) provides high-end HPC and the by today largest German data capacities for scientists at FZJ, in the Helmholtz Association, at universities and at research laboratories in Germany and all over Europe (via PRACE) as well as for industrial partners. The facility is contributing to the development of modular supercomputing and future data center technology, aiming at exascale for supercomputing and data management systems in collaboration with world-class manufacturers and users, and has been selected by EuroHPC JU to become the first European exascale facility. The facility is carrying out and will enhance its research and development for advanced computing architectures such as quantum computers, quantum simulators, quantum annealers, digital annealers and neuromorphic computers. A further important task of the facility is the user support, education and training.

JSC has set up the Jülich UNified Infrastructure for Quantum computing (JUNIQ) in the form of a single, user-friendly platform (QC-PaaS). It offers user support and access to quantum computer (QC) emulators and QC technologies at various stages of technological maturity. JUNIQ is the local platform to integrate QCs and quantum annealers in the form of quantum-classical hybrid computing systems into JSC's modular HPC environment.

Role within QSolid

Within the QSolid project, JSC is involved in work packages 9 and 10.

In WP9, JSC will define classes of optimisation, solid state physics and Earth observation problems that can be efficiently mapped to a 1D quantum chip architecture. JSC will implement these applications on available QC hardware (OpenSuperQ, IBM Q Experience, ...) as well as on the QSolid hardware available by then for cross-platform benchmarking. Furthermore, JSC will simulate the execution of the algorithms for these applications on an ideal 1D QC with perfectly coherent qubits and on a 1D QC with errors introduced, which leads to non-coherent qubits. JSC will estimate the maximum for decoherence that is still compatible with the expected result on the ideal QC without errors. The simulation and benchmarking results will be collected in a benchmarking suite. For the co-design goal of WP1, JSC will perform simple algorithms (repetitive gate sequences, QFT, ...) on emulators and available gate-based QC hardware and make the results available to WP1.

In WP10, JSC will design the QSolid portal starting from the architecture of the existing JupyterHub solution in production at JSC. In addition, JSC will prepare and implement the integration of the management of the system, user access management and health check for uptime and availability of the QC hardware into the JSC modular supercomputer architecture.
