Hybrid boson sampling-neural network architecture for enhanced classification
A preprint on arXiv describes a hybrid machine-learning architecture in which boson sampling feeds into a neural network for classification. The authors argue that two known problems stand in the way of quantum advantage for classical learning tasks: datasets that are too large and complex, and quantum hardware that is still constrained. They identify boson sampling as a candidate resource that might bypass some of those limits.

If the proposed boson-sampling front end can be implemented on existing photonic sampling hardware, it could provide a concrete benchmark for quantum advantage on classification tasks within two years, giving photonic platforms an early test case against classical neural networks.
Boson sampling processors already exist at small scale, and classical neural-network back ends are well understood; the main open question is whether the hybrid representation is useful enough on standard datasets to outperform classical baselines or reduce resource requirements.
