The paper studies the expressivity of Instantaneous Quantum Polynomial (IQP) feature‑map quantum kernels by deriving a Fourier representation of their associated Reproducing Kernel Hilbert Space (RKHS). It identifies three bandwidth regimes—localized, multimodal, and periodic—each with distinct expressive properties, and demonstrates these regimes on synthetic datasets for classification and anomaly detection, comparing against a classical Gaussian kernel. The work provides a clear link between the kernel’s accessible frequencies, its bandwidth hyperparameter, and the structure of the data, offering guidance for bandwidth selection when data exhibit known periodic or multimodal patterns.

arXiv:2604. 26675v2 Announce Type: replace-cross Abstract: We investigate variational quantum classifiers (VQCs) for land-cover classification from multispectral satellite imagery, adopting a feature-map perspective in which the quantum circuit defines a nonlinear data embedding while the readout determines how this representation is exploited.
