Abstract

This survey analyses how five key mechanisms—Quantum Key Distribution (QKD), Quantum Secure Direct Communication (QSDC), entanglement-enhanced sensing, Quantum Clock Synchronization (QCS), and quantum teleportation/entanglement swapping—map onto the core metrological attributes of accuracy, stability, sensitivity, synchronization, security, and traceability. The paper identifies the principal research gaps—in particular, scalable entanglement distribution, hybrid classical–quantum integration, and SI-traceable calibration of quantum devices—and the technical advances required to translate laboratory prototypes (e.g. QKD links, QSDC networks, entangled-clock arrays, and QCS demonstrators) into field deployable quantum-enabled metrology.
