Researchers have compared the performance of quaternion-valued neural networks against shallow variational quantum circuits (VQCs) on classical supervised learning tasks. The study found that quaternion networks generally matched or approached the performance of real-valued neural networks across benchmarks like MNIST, Fashion-MNIST, and CIFAR-10. In contrast, shallow VQCs showed lower accuracy and higher computational costs, indicating that the shared local SU(2) geometry is insufficient to confer a practical quantum advantage in these scenarios.
