NEW YORK—A team of quantum computing engineers from JPMorgan Chase & Co., Toshiba Corp. and Ciena Corp. say they have successfully shown that a powerful, newly-developed encryption network can be used to protect communications on the blockchain, according to a paper published Thursday.
The group of researchers say it is the first time that a quantum key distribution (QKD) network, a super-secure two-way communication network powered by quantum physics, has been tested as a way to protect the blockchain from quantum computing attacks.
