In tests on CESNET-derived traffic, the full-hybrid Quantum Neural Network achieved mean AUCs of 0.9981, 0.9974, and 0.9941 and reduced false-positive rates relative to ExtraTrees by 44.6%, 49.6%, and 67.9% across random, entity-group, and temporal holdouts.", "body_md": "arXiv:2608.18572v1 Announce Type: cross\nAbstract: Tactile Internet services couple cyber events directly to physical actuation, so security decisions must improve risk discrimination without perturbing the control path. This paper presents VQC-ZTI, a split-plane Variational Quantum Classifier framework for zero-trust protection of Tactile Internet services, in which an off-path VQC analyzes encrypted-flow telemetry while an on-path policy engine applies cached deterministic grant, restrict, step-up, and deny actions. By decoupling anomaly scoring from enforcement, VQC-ZTI preserves predictable control behavior and allows detector sensitivity and policy aggressiveness to be tuned independently. We evaluate the framework on CESNET-derived aggregated traffic using random, entity-group, and temporal holdouts with a hybrid PyTorch-PennyLane implementation. The full-hybrid Quantum Neural Network achieves mean areas under the receiver operating characteristic curve of 0.9981, 0.9974, and 0.9941 and reduces the false-positive rate relative to ExtraTrees by 44.6%, 49.6%, and 67.9%, respectively. A representative component-timing decomposition further illustrates that batched VQC scoring remains in the asynchronous evidence path rather than the immediate enforcement path.", "url": "https://wpnews.pro/news/vqc-zti-variational-quantum-control-for-zero-trust-protection-of-the-tactile", "canonical_source": "https://www.machinebrief.com/news/vqc-zti-variational-quantum-control-for-zero-trust-protectio-crtc", "published_at": "2026-08-21 04:00:00+00:00", "updated_at": "2026-08-21 05:43:07.641213+00:00", "lang": "en", "topics": ["artificial-intelligence", "machine-learning"], "entities": ["VQC-ZTI", "arXiv", "CESNET", "PyTorch", "PennyLane", "ExtraTrees"], "alternates": {"html": "https://wpnews.pro/news/vqc-zti-variational-quantum-control-for-zero-trust-protection-of-the-tactile", "markdown": "https://wpnews.pro/news/vqc-zti-variational-quantum-control-for-zero-trust-protection-of-the-tactile.md", "text": "https://wpnews.pro/news/vqc-zti-variational-quantum-control-for-zero-trust-protection-of-the-tactile.txt", "jsonld": "https://wpnews.pro/news/vqc-zti-variational-quantum-control-for-zero-trust-protection-of-the-tactile.jsonld"}}
