Method for ultrafast, secure communication using fiber optics systems

總結

The ability to establish and monitor a secure connection between two parties is an essential component of a secure communication system. Quantum Key Distribution (QKD) is a technique that leverages the underlying physics of quantum mechanical interactions to share a secure connection while preventing interception. However, existing QKD protocols rely on quantum properties that suffer from low data transfer rates and are sensitive to external effects, reducing their practicality. This technology, called High-Dimensional Temporal Quantum Key Distribution (HDT-QKD), employs dispersive optics to generate an ultrafast secure connection, with data transfer speeds over 100 Mbps over distances exceeding 200 km, and is compatible with existing fiber optics communication systems.
