Our paper "Towards a Unified Architectural Representation in HPCQC: Extending sys-sage for Quantum Technologies" was accepted for ISC 2025 and has won the prestigious Hans Meuer Award. The work is based on a Master Thesis of Durganshu Mishra, which he wrote at CAPS. The paper was written in collaboration between CAPS and LRZ. The authors are Durganshu Mishra (CAPS), Stepan Vanecek (CAPS), Jorge Echavarria (LRZ), Xiaolong Deng (LRZ), Burak Mete (LRZ), Laura Schulz (LRZ), Martin Schulz (CAPS).
The paper proposes a novel way of representing and providing HPCQC resources and their topological information for further use for compilers, schedulers, and circuit mappers, facilitating the integration of Quantum resources in HPC environments. The work extends the sys-sage library, an originally HPC-focussed library originally developed also at CAPS.
The paper will be presented on Tuesday 10th at ISC 2025 in Hamburg.
Abstract—Quantum Computing (QC) presents a significant
departure from and substantial parallels to classical computing.
Some such parallels include the need to understand topology
and system characteristics information and make that available
to users as well as other system components like compilers,
runtimes, and schedulers.
We analyze the differences and extend sys-sage to capture
quantum information. This leverages code reuse and automat-
ically incorporates QC information into the software stack for
hybrid HPCQC integration. This paper addresses the extensions
to sys-sage, a classical HPC-relevant library, to also represent and
store the characteristics of Quantum Processing Units (QPUs).
Our work also presents the role of sys-sage in pre-processing
and analyzing the topology and properties of different com-
ponents of QCs to provide valuable insights that compilers,
schedulers or circuit mappers can use. These features aim to
facilitate the HPCQC ecosystem by providing a unified interface.
