SBQE in Image Classification
On the Fashion-MNIST dataset, SBQE achieves 80.95% accuracy, outperforming amplitude encoding by 2.0% and a linear MLP by 1.3%. This demonstrates SBQE's ability to leverage the classical redistribution of shots for robust performance without deep quantum encoding circuits. For Semeion handwritten digits, SBQE reached 89.1% accuracy, effectively matching a width-matched classical network.
Takeaway: SBQE significantly reduces the error gap to classical models by exploiting existing hardware resources (shots) more effectively.
