Researchers have introduced McQuack, a novel quantum kernel method designed for multiclass classification problems. This method addresses limitations of traditional kernel methods by achieving linear scaling with the number of training samples, replacing the full Gram matrix with a trainable sample-to-class-centroid fidelity matrix. McQuack demonstrated superior performance compared to existing quantum baselines in simulations and achieved results comparable to an RBF kernel on IBM quantum devices, even without training. AI
