A new research paper compares classical SU(2) models with variational quantum circuits (VQCs) on various vision benchmarks. The study found that quaternion-valued neural networks, a type of classical SU(2) model, performed comparably to or better than shallow VQCs across datasets like MNIST, Fashion-MNIST, and CIFAR-10. While quaternion networks maintained a high percentage of real-valued network performance, VQCs showed lower accuracy and higher computational costs, suggesting that classical SU(2) geometry can be an efficient alternative to shallow quantum circuits for tasks lacking inherent quantum structure.
