Quantum cryptography links integration on commercial wide-area optical networks using Wavelength division multiplexing (WDM) is essential to develop global scale Quantum Key Distribution Networks (QKD)

WDMQKD

Quantum key distribution (QKD), establishes highly secure keys between distant parties by using single photons to transmit each bit of the key. A unique aspect of quantum cryptography is that Heisenberg’s uncertainty principle ensures that any attempts to intercept and…...
