Researchers from JPMorgan Chase, Toshiba, and Ciena have developed a quantum key distribution (QKD) network designed to secure blockchain applications against potential quantum attacks.
The QKD network functions as a secure two-way communications system that can instantly detect and neutralize eavesdroppers. The team also examined how realistic environmental factors affect the quality of the quantum channel and successfully employed a QKD-secured optical channel to protect Liink, JPMorgan’s production-grade peer-to-peer blockchain network.
Marco Pistoia, distinguished engineer and head of the Flare Research group at JPMorgan Chase, emphasized the importance of security, stating, "This work comes at an important time as we continue to prepare for the introduction of production-quality quantum computers, which will change the security landscape of technologies like blockchain and cryptocurrency in the foreseeable future."
