Abstract: Quantum Computing (QC) is emerging as a new computing paradigm with substantial promise for targeted workloads. What is already clear is that that QC at usable scale will only be helpful in combination with HPC. Consequently, effort towards a tight integration of the two technologies is needed and questions are being raised, such as: (1) how should quantum acceleration be integrated into HPC systems, (2) when will QC to mature enough to enable integration, and (3) which applications can truly maximum the benefit of HPC and QC together?
Long Description: Quantum Computing (QC) is emerging as a new computing paradigm with substantial promise
for targeted workloads. Major investments in future quantum devices are being made by large
companies and small startups alike, and the number of qubits is steadily rising. At the same
time, advances in quantum algorithms, quantum simulation as well as the use of analog
quantum systems, such as annealers, are showing potential.
It is clear, though, that QC can only work in combination with, and integrated into, the HPC
ecosystem. This will enable the use of quantum acceleration for particular problems in
combination with HPC platforms for hybrid executions as well as the facilitation of needed data
staging and resource management. Additionally, HPC can support QC optimizations, e.g., for
complex, optimized quantum compilation, error control or dynamic topology adaptation.
In this BoF, we will bring together experts from the physics/quantum computing community
and the HPC community to discuss the potential and possible avenues for such integration at
both the hardware and at the software levels. This could include connection strategies of the
two devices at the network, the OS or even the process level, or the inclusion of active resource
management inside the QC control infrastructure. Further, we will look at different use cases
across QC technology (including superconducting qubits and ion-traps) and explore how such
integration could work, when it will reach the needed maturity level, and what could be the
benefit at of such integration for different systems and problem sizes.
The content of this BoF will be formed around a prior workshop held by the same organizers at
IEEE Quantum Week, which will discuss the view from the physics side. In this BoF, it is our goal
to bring this view into the HPC community, enable the HPC community to react and to
ultimately bridge the two worlds with the goal of a unified view on HPC-QC. Our goal is to start early in this technology evolution to avoid silos, facilitate the formation of a common language,
and to enable co-design between QC users, QC platform providers and HPC integrators.
We explicitly avoid the selection of concrete speakers at this point, as this is a quickly moving
topic with several ongoing and starting initiatives across all continents. Further, the three
organizers will explore this topic at IEEE Quantum Week with a workshop that includes a
contributed program; we will use that event to drive the speaker and topic selection for this
BoF. We are considering speakers from major companies working on QC systems (Intel,
Microsoft, IQM, AQT, …) as well as QC system software (ParityQC, CQC, Strangeworks, …), as
well as academic partners pushing the HPC-QC integration boundaries.
