Major banking consortiums have initiated commercial deployments of Quantum Key Distribution (QKD) networks across core optical fiber channels. The move aims to safeguard critical financial clearing systems against post-quantum cryptographic vulnerabilities.
Infrastructure Costs and Interoperability
While initial QKD deployment requires specialized optical repeaters and dedicated fiber lines, regulatory bodies are signaling future mandates for post-quantum resilience, driving early infrastructure investment among top-tier financial service providers.
