Researchers have developed a new training law for noisy equivariant quantum neural networks that leverages symmetry to maintain trainability even in the presence of noise. The law identifies a specific physical quantity, the readout-visible aligned coherence rate, which governs how quickly gradients decay. This rate is calculated as a Rayleigh quotient of the noise generator along the gradient-carrying mode. Density-matrix simulations confirm that the model's degradation under finite noise follows this law, with a high coefficient of determination, outperforming standard channel diagnostics. AI
