//! Quantum kernels for quantum machine learning.
//!
//! * [`quantum_kernel`] — the global overlap (fidelity) kernel
//!   `k(x,y)=|⟨ψ(x)|ψ(y)⟩|²`.
//! * [`projected`] — projected quantum kernels (PQK) over single-qubit reduced
//!   observables, avoiding the exponential concentration of the fidelity kernel.
//! * [`trainable`] — trainable quantum embedding kernels optimized by
//!   kernel-target alignment.
