Researchers have developed a new theoretical framework for representation learning using quantum signal processing (QSP). This approach allows for the computation of the quantum neural tangent kernel, revealing an input-dependent angular geometry that remains non-self-averaging even with random unitaries. The study also provides a sparse-data guarantee for the nonlinear gradient flow, demonstrating convergence to an integrable scalar flow with explicit convergence times, and identifies a finite-depth speed limit for training dynamics.
