The future of quantum computing is quantum-classical hybrid computation: quantum computing devices coupled with classical supercomputers running workflows making use of CPUs, GPUs, and Quantum Processing Units (QPUs) to solve real-world problems.
This fully hybrid computing is a challenge given the typical cloud access of QPUs, and typical High Performance Computing (HPC) systems are also not geared towards multi-stage heterogeneous workflows.
I will present QBitBridge, a framework for hybrid, multi-QPU, workflows running on HPC systems with tight integration into HPC job schedulers such as SLURM that makes use of Prefect and virtual QPUs (vQPU) running on NVIDIA GraceHopper superchips at the Pawsey Supercomputing Research Centre.
This framework is also extendable to cloud-accessible QPUs. I will also present work developing HPC-friendly vQPU, HPC-vQPU, aimed at hardware exploration and HPC exploitation: one in which we can define vQPUs with specific connectivity, noise models, and native gates and run simulations at scale.
I also discuss how we aim to abstract away QPUs while still enabling closer-to-hardware exploitation using DynQ, a quantum virtual machine. I will finish with a look forward and how we integrate these technologies to enable real-world use of QPUs.
