Quantum MeanFlow: single-shot generative sampling on NISQ hardware
A new arXiv preprint introduces Quantum MeanFlow, a quantum analogue of flow matching for generative sampling on noisy intermediate-scale quantum hardware. The abstract positions the work within quantum generative models exploring whether quantum computation can improve generative machine learning. It describes flow matching as generating samples by transporting a simple known distribution to a target data distribution with a learned velocity field, with Quantum MeanFlow presented as the quantum counterpart.

If Quantum MeanFlow achieves true single-shot sampling without repeated circuit executions, it could make evaluating quantum generative models on existing NISQ devices practical enough for near-term benchmarking against classical baselines.
Single-shot sampling would remove a major overhead that currently forces quantum generative models to run many circuit executions per generated sample, a bottleneck on small noisy devices. Existing NISQ processors are already accessible, so the remaining gate is whether the method's sample quality holds on real hardware.
