Interconnects for next generation hybrid quantum-classical systems

Project funded by Swedish Governmental Agency for Innovation Systems (Vinnova) (Project grant), grant 2024-00448_Vinnova. Participating organisations named by the source: Ericsson AB. Funded amount: SEK 1,571,100, as stated by the source. Runs 2024-06-25 to 2025-02-25. Keywords: Oklassificerat, Unclassified.

Abstract given by the source: Purpose and goal: Quantum Computing (QC) systems have the potential to offer a distinct advantage in addressing real-world problems that are challenging for classical computing alone, even on powerful high-performance computing (HPC) systems. We propose a mixed machine model to abstract QC systems (non-Von Neumann architecture) with integration to HPC (Von Neumann architecture), and a performance model for assessing applications at different scales on a target architecture. Expected results and effects: We will develop a hierarchical machine model to encapsulate the distinctive features of components in an integrated QC-HPC system, and their interconnects at different granularities with jitter and synchronization characteristics. As proof of concept, two quantum applications, a reinforcement learning application used in antenna tiling and a variational quantum application used in drug discovery, will be considered and optimized at different QC- HPC interconnects and scales of QC systems using the developed models. Approach and implementation: The project is divided into four work packages. WP1 Modelling consists of a state-of-the-art review and the development of the machine model of general QC-HPC systems. WP2 Applications consists of a state-of-the-art review and the design of two hybrid QC-HPC applications. WP3 Evaluation consists of the integration and validation of the two applications on the simulation model, and the evaluation of scalability changes in QC- HPC interconnects at different scales of QC systems. WP4 Management consists of the management and the dissemination of the project.
