Abstract
Next-generation industrial automation in Industry 5.0 demands sub-nanosecond time synchronization to enable advanced human-machine collaboration and real-time control systems. Quantum Time Synchronization (QTS), enabled by entangled photon-based quantum networks, offers ultra-precise clock alignment across distributed nodes. However, practical deployment requires an authenticated classical communication channel to exchange timestamped data and extract synchronization offsets. This paper investigates the core tradeoffs between classical channel latency and achievable QTS precision in hybrid quantum-classical networks. Using a discrete-event simulator, we evaluate the impact of various classical network protocols, each with distinct latency characteristics, on QTS performance. Our results demonstrate that even modest latency increases result in degraded synchronization accuracy and increased synchronization jitter, particularly in time-critical industrial contexts. To address these challenges, we propose a combined approach that integrates low-overhead authentication, low-latency communication protocols, and predictive clock drift compensation. Our findings provide actionable guidance for balancing latency, security, and synchronization accuracy in QTS services for future networks.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
