Quantum Key Distribution


QKD, also known as quantum cryptography, secures the distribution of symmetric encryption keys by sending photons – quantum particles of light – across an optical link.

In quantum physics observation causes perturbation, making it possible to identify if keys have been intercepted. This guarantees long-term confidentiality and data integrity at a time when the demand on networks, and the threats they face, has never been greater.
