Integrating Quantum and High Performance Computers for Practical Quantum Computing

Presenter:
Kristel Michielsen, Juelich Supercomputing Centre (JSC)

Description:
For practical quantum computing, HPC infrastructures will integrate quantum computers and simulators (QCS) in addition to cloud access to stand-alone QCS.

As longterm experience in conventional supercomputing demonstrate, the successful integration of QCS into HPC systems requires a focus on all three fundamental components of the HPC ecosystem: users and their applications, software, and hardware.

The strategy of the Jülich Supercomputing Centre (JSC) for quantum computing is based on three pillars. The first pillar is based on the classification of quantum computers as “analog” or “digital” systems and their intermediate stages, aiming at the provision of all these variants. The goal is to use QCS with a high enough technological maturity as pilot production systems. The second pillar of JSC’s strategy is the tightest possible integration of QCS into JSC’s HPC systems. For this purpose, JSC employs the concept of the modular supercomputer architecture (MSA). The QCS are used as modules in the MSA, closely coupled with other specific modules such as the general purpose CPU and GPU acceleration systems or a tiered common high speed storage. Modular operation requires joint scheduling that will ensure an efficient exploitation of available resources. The third pillar of JSC’s quantum computing strategy is the creation of a world-leading quantum computer user infrastructure. This includes the technical provision of the QCS (integrated into the HPC environment) – under European legislation – the deployment of the systems via peer-reviewed calls for proposals, the support of the users in simulation labs, algorithm development groups and cooperative research. These activities are carried out in the Jülich UNified Infrastructure for Quantum computing (JUNIQ).

By coordinating the EuroHPC JU project HPCQS, JSC together with European partners from science, engineering and industry is bringing the principle of JUNIQ to the European level, with JUNIQ forming a nucleus in an integrated and federated EuroQCS (European Quantum Computing and Simulation) infrastructure.
