    "body_text": "The study tests whether nitrogen-vacancy sensors can provide a physical channel when manipulated digital power-grid telemetry still looks plausible. Under a matched budget of 40 physical trials per sensor in the IEEE 14-bus simulation, quantum computational sensing reached 0.944 average precision, versus 0.800 for conventional four-setting readout and 0.751 for tomography; the low-budget ordering persisted in the 30- and 118-bus cases. Multi-setting methods recovered with larger budgets, and improved quantum sensitivity did not always yield task-relevant state separation. This is simulation evidence with Lindblad sensor models, not a field deployment.",
