Distance-Encoded Quantum Kernels for Spatial Estimation: Design Criteria and NISQ Hardware Characterization

Year: 2026
Type: article
Abstract: Ordinary kriging relies on a positive semi-definite (PSD) covariance matrix derived from a fitted variogram model. This study investigates whether quantum kernel matrices can replace variogram-based covariance functions in the kriging system — and establishes the circuit design criteria under which such replacement is mathematically valid and practically useful.
