US-based banking heavyweight JPMorgan Chase has reportedly disclosed details related to its study regarding a quantum key distribution (QKD) blockchain network, with resistant features against quantum computing attacks.

Specifically, QKD is reportedly going to take advantage of quantum mechanics and cryptography to offer facilitating features for the exchange of secure data for both sides, as well as discovering and shielding against third parties’ efforts to eavesdrop on the exchange. 

The tech is reportedly considered a suitable defense against possible blockchain attacks, which could be carried out by quantum computers in the long run.

JPMorgan reportedly forged a partnership with Toshiba and Ciena to collaborate on the deployment and testing of the QKD blockchain

“At this time, QKD is the only solution that has been mathematically proven to defend against a potential quantum computing-based attack, with security guarantees based on the laws of quantum physics” The announcement reportedly claimed. 

The research was reportedly carried out to be utilized for metropolitan territories and managed to generate noteworthy outcomes, nominally possessing the ability to “support 800 Gbps data rates for mission-critical applications under real-world environmental conditions.”

“The proof of concept network infrastructure relied on Toshiba’s Multiplexed QKD System, manufactured by Toshiba Europe at their Cambridge UK base, and Ciena’s Waveserver 5 platform, equipped with 800 Gbps optical-layer encryption and open APIs running over Ciena’s 6500 photonic solution”.

Marco Pistoia, engineer and head of the Flare Research group at JPMorgan Chase, further highlighted the crucial role of designing secure blockchain infrastructure, prior to the official introduction of quantum computing to the market.
