Quantum Xchange Collaborates with Toshiba to Double the Capacity of the Phio Network

By IQT News posted 26 Apr 2019

(HelpNetSecurity) Quantum Xchange, provider of the first quantum key distribution (QKD) network in the U.S., has collaborated with Toshiba Corporation to double the capacity of the Phio network.
Toshiba’s QKD system offers multiplexing compatibility, which doubles network capacity by allowing the control channel and the quantum channel to be transmitted on one fiber. As a result, QKD transmissions have taken place across the Hudson River on one fiber, where two were previously required. “We are very fortunate to have had the opportunity to test our product on an operational network in New York City,” said Shinya Murai, QKD Project Manager of Toshiba Corp.
Currently, the ultra-secure, quantum network is used to securely transmit high-value data, including trading algorithms and customer settlement accounts, for several large banks and asset management firms. Quantum Xchange plans to extend Phio nationwide by year’s end.
