In particular, quantum kernel methods have been demonstrated to be able to learn certain classically intractable functions efficiently if the kernel is well-aligned with the target function. In the more general case, quantum kernels are known to suffer from exponential \"flattening\" of the spectrum as the number of qubits grows, preventing generalization and necessitating the control of the inductive bias by hyperparameters.
