U.S. bank JPMorgan Chase unveiled a study of the Quantum Key Distribution (QKD) network, which is resistant to quantum computing attacks.
QKD uses quantum mechanics and cryptography to allow two parties to exchange secure data. In addition, the network allows it to calculate third parties who are trying to eavesdrop on the exchange.
According to the Feb. 17 announcement, JPMorgan partnered with Toshiba and Ciena to test QKD for blockchain applications.
“QKD is currently the only solution that has been mathematically proven to protect against a potential attack based on quantum computing with security guarantees based on the laws of quantum physics,” the announcement said.
The study reports that the network supports data rates of 800 Gbps for mission-critical applications in real-world environments.
“This work comes at an important time as we continue to prepare for the introduction of production-quality quantum computers that will change the security landscape of technologies such as blockchain and cryptocurrency for the foreseeable future,” said engineer and head of the FLARE research group at JPMorgan Chase Marco Pistoia.
