arXiv:2608. 04047v1 Announce Type: cross Abstract: Conventional BB84 Quantum Key Distribution (QKD) systems rely on a fixed 11% Quantum Bit Error Rate (QBER) threshold to detect eavesdropping.
arXiv:2604. 10933v2 Announce Type: replace-cross Abstract: Deep neural networks remain highly vulnerable to adversarial perturbations, limiting their reliability in security- and safety-critical applications.
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.
The paper investigates whether noise in quantum hardware limits the performance of quantum kernel methods for network intrusion detection. Using Pegasos-QSVC on the NSL-KDD and ToN-IoT datasets, the authors run 56 experiments across noiseless and noisy backends, finding that quantum models achieve lower accuracies than classical XGBoost and exhibit high seed-dependent variability, including degenerate classifiers. Kernel Gram matrix analysis shows low effective rank and severe ill-conditioning even without noise, indicating intrinsic fragility in the quantum representation.
