A consortium of international banking institutions has initiated live network trials of quantum key distribution (QKD) across dedicated fiber-optic corridors. The initiative aims to protect financial transfer routing against future quantum computer decryption capabilities.
Hardware Standardization and Distance Limitations
Current QKD deployments are constrained by optical fiber attenuation, necessitating trusted relay nodes every 100 kilometers. Engineers are testing integrated quantum repeaters to eliminate physical security risks associated with intermediary routing centers.
