QDMI at ISC 2025: Connecting quantum hardware and software
Lukas Burgholzer’s QDMI contribution to the QRUCH workshop addressed the software interfaces needed to connect quantum resources with HPC.
ISC High Performance brought the computing community to Hamburg on 10–13 June 2025. Its quantum program included the first QRUCH — Quantum Resources for Unified Computing Hub workshop, focused on the software needed to integrate quantum computers into HPC centers.
Lukas Burgholzer contributed a lightning talk on the Quantum Device Management Interface (QDMI). The workshop program lists his contribution on 13 June under his Technical University of Munich affiliation; the presentation slides are available from the organizers.
Making device information usable
Quantum software needs information about the hardware it targets: available operations, device characteristics, and constraints that affect compilation. The QDMI presentation examined how hardware providers can expose that information through a common interface and how software tools can use it.
The slides placed QDMI within the Munich Quantum Software Stack and the wider Munich Quantum Valley effort. They connected the interface to device selection, compilation, and execution, showing why the boundary between hardware and software matters for the whole stack.
From interfaces to computing-center workflows
The workshop also covered authentication, accounting, job scheduling, and hybrid classical–quantum workflows. These concerns extend beyond running an individual quantum circuit: computing centers need resources that fit their existing operational environment.
For the quantum software community, the session provided a shared setting to compare integration approaches. QDMI’s open specification and implementation give developers concrete material to inspect, test, and build on.
