Abstract
A quantum cryptographic key distribution (QKD) relay () includes one or more interfaces (-through-N) and processing logic (). The one or more interfaces (-through-N) receive secret keys from other QKD relays in a QKD network. The processing logic () determines one or more paths for transporting the secret keys, using quantum cryptographic techniques, across a QKD network and route the secret keys towards a respective destination across the QKD network using the determined one or more paths.
