Abstract
We conducted a systematic survey of emerging quantum-HPC platforms, which integrate quantum computers and High-Performance Computing (HPC) systems through co-location. Currently, it remains unclear whether such platforms provide tangible benefits for near-future industrial applications. To address this, we examined the impact of co-location on latency reduction, bandwidth enhancement, and advanced job scheduling. Additionally, we assessed how HPC-level capabilities could enhance hybrid algorithm performance, support large-scale error mitigation, and facilitate complex quantum circuit partitioning and optimization. Our findings demonstrate that co-locating quantum and HPC systems can yield measurable improvements in overall hybrid job throughput. We also observe that large-scale real-world problems can require HPC-level computational resources for executing hybrid algorithms.
