MQSC at SCA/HPCAsia 2026: From software stacks to compiler integration
In Osaka, Lukas Burgholzer and Patrick Hopf joined the HPC community to discuss quantum software stacks and practical compiler integration.
SCA/HPCAsia 2026 brought the high-performance computing community to the Osaka International Convention Center on 26–29 January 2026. MQSC team members Lukas Burgholzer and Patrick Hopf attended with work on two connected topics: coordinating quantum and classical resources, and integrating quantum software tools into compiler infrastructure.
Discussing the stack as a whole
Lukas presented the joint paper The Munich Quantum Software Stack. The work describes how applications, compilers, scheduling, and device interfaces fit together in hybrid quantum–classical workflows.
The paper brings together authors from the Technical University of Munich, Leibniz Supercomputing Centre, MQSC, Argonne National Laboratory, and Software Competence Center Hagenberg. The stack is developed within the Munich Quantum Valley ecosystem.
Its architecture connects application frameworks to an HPC-integrated scheduler, MLIR-based compilation, and the Quantum Device Management Interface (QDMI). The paper also distinguishes implemented components from capabilities still under development, including requirements for future fault-tolerant systems.
Making compiler tools work together
The same research session on 27 January included Integrating Quantum Software Tools with(in) MLIR, co-authored by Patrick, Lukas, and colleagues. It addresses a practical problem: useful quantum software tools are often developed separately, making them difficult to combine.
The paper uses the integration of Xanadu’s PennyLane with the Munich Quantum Toolkit as a case study. It explains the engineering steps and lessons involved in connecting existing tools through MLIR.
Together, these contributions gave the HPC audience two views of quantum software integration: the architecture that coordinates resources and the compiler interfaces that let individual tools participate. The papers provide the technical detail for readers who want to explore either topic further.
