Paper CC-BY-SA

Quantum programs are usually executed via cloud-based services and compiled at runtime. This results in substantial overhead during runtime due to compilation, especially as programs grow in size and complexity. We examined the cumulative runtime of individual compilation passes and identified those that most strongly impact the overall runtime. We submitted our preliminary work as a contribution to the 2025 IEEE International Workshop on Quantum Computing: Circuits, Systems, Automation, and Applications (QC-CSAA), held in conjunction with the 2025 ISVLSI conference. Our work has been accepted for presentation as a full paper. You can find the preprint here.

Compilation time significantly impacts quantum program execution. We analyzed the quantum circuit compilation in Qiskit, focusing on the cumulative runtime of each task and identifying those with the strongest impact on the overall runtime.

Quantum Computing as a Service (QCaaS) offers access to quantum hardware without the need for costly infrastructure investments. However, integrating quantum applications into existing classical systems poses significant challenges.
