Quantum computers are a key emerging technology, particularly for specific kinds of problems that require enormous computing power. However, integrating quantum systems into existing supercomputers poses a challenge. Researchers at the Technical University of Munich (TUM) have developed a tool that combines quantum and supercomputers and enables them to interact seamlessly. This approach has been demonstrated experimentally in collaboration with a team at the Leibniz Supercomputing Centre (LRZ).

Quantum computers operate using qubits, which, unlike classical bits, can exist in multiple states simultaneously through superposition. Additionally, qubits can be entangled, allowing for new computational paradigms that outperform classical systems for specific tasks. However, quantum computers are not universally applicable and are not intended to replace traditional high-performance computing (HPC). Instead, they are envisioned as a complementary accelerator within the HPC landscape.

Integrating quantum systems into HPC environments is complex due to differences in architecture, interfaces, and control mechanisms. “By developing the hybrid tool called sys-sage, we have addressed some of these challenges,” says Martin Schulz, Professor of Computer Architecture and Parallel Systems at TUM and member of the LRZ Board of Directors.
