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.
arXiv:2607. 19782v1 Announce Type: cross Abstract: Kernel methods are powerful tools in machine learning but commonly used full-Gram kernels face three key limitations: (1) quadratic scaling with training set size; (2) the use of fixed, non-trainable kernels; and (3) the absence of an intrinsic formulation for multiclass classification.
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.

The paper introduces Neural Fourier Surrogates (NFS), a stochastic classical neural network that learns coefficients over a finite Fourier series support similar to quantum neural networks (QNNs). By testing on tabular benchmark datasets, NFS demonstrates competitive classification performance against established classical baselines and data‑reuploading QNNs. The authors also compare the learned Fourier spectra of QNNs and NFS on synthetic data, positioning NFS as a natural classical baseline for evaluating QNN performance.
