High Performance Computer and Quantum Simulator hybrid

Project description

Integrating quantum simulators with classical supercomputers

The integration of quantum simulators in existing European supercomputers is the aim of the HPCQS project, funded by the European High Performance Computing Joint Undertaking (EuroHPC JU). Using an innovative approach to prepare Europe for the post-exascale era, the project will integrate two quantum simulators (each controlling about 100+ quantum bits) in two supercomputers. The first is the Joliot Curie of GENCI, the French national High Performance Computing organisation. The second is the JUWELS of Germany’s Jülich Supercomputing Centre. By integrating quantum hardware with classical computing resources, research entities and industries will be able to solve complex challenges in areas such as materials and drug design, logistics and transportation.


The aim of HPCQS is to prepare European research, industry and society for the use and federal operation of quantum computers and simulators. These are future computing technologies that are promising to overcome the most difficult computational challenges. HPCQS is developing the programming platform for the quantum simulator, which is based on the European ATOS Quantum Learning Machine (QLM), and the deep, low-latency integration into modular HPC systems based on ParTec’s European modular supercomputing concept. A twin pilot system, developed as a prototype by the European company Pasqal, will be implemented and integrated at CEA/TGCC (France) and FZJ/JSC (Germany), both hosts of European Tier-0 HPC systems. The pre-exascale sites BSC (Spain) and CINECA (Italy) as well as ICECH (Ireland) will be connected to the TGCC and JSC via the European data infrastructure FENIX. It is planned to offer quantum HPC hybrid resources to the public via the access channels of PRACE. To achieve these goals, HPCQS brings together leading quantum and supercomputer experts from science and industry, thus creating an incubator for practical quantum HPC hybrid computing that is unique in the world. The HPC-QS technology will be developed in a co-design process together with selected exemplary use cases from chemistry, physics, optimization and machine learning suitable for quantum HPC hybrid calculations. HPCQS fits squarely to the challenges and scope of the call by acquiring a quantum device with two times 100+ neutral atoms. HPCQS develops the connection between the classical supercomputer and the quantum simulator by deep integration in the modular supercomputing architecture and will provide cloud access and middleware for programming and execution of applications on the quantum simulator through the QLM, as well as a Jupyter-Hub platform with safe access guarantee through the European UNICORE system to its ecosystem of quantum programming facilities and application libraries.
