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. Launched in June 2018, Phio from
Quantum Xchange, is the first nationwide QKD network in the U.S.
Toshiba’s prototype QKD system, which delivers digital keys for
cryptographic applications on fiber optic computer networks, has been
successfully demonstrated on the initial phase of the Phio network –
connecting the financial markets on Wall Street with back office
operations in New Jersey.

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. This doubling of capacity provides twice the key
material previously available as well as increasing availability of
transmission while greatly reducing the number of fibers required for
customers to access the Phio network.
“It was a pleasure working with Toshiba to test their equipment on our
operational QKD network,” said John Prisco, CEO and Founder of Quantum
Xchange. “Developments like those made by Toshiba will catapult QKD into
the mainstream. Increased network capacity will make the technology more
user-friendly, and deployment and operational costs will be kept low,
making the quantum technology a viable option for all organizations
working to secure their most critical data.”
Developments in QKD technology are essential to future communications
systems worldwide and keeping critical data safe in years to come. QKD
technology promises unprecedented secrecy and assures that organizations
can protect their critical data from harvesting attacks and the imminent
threat of quantum computers. The technology is complementary to
public-key encryption (PKE), allowing organizations to secure their
current networks by adopting trusted, verifiable, symmetric keys which
use quantum physics to detect anyone intruding on a transmission.
“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. “Our stabilization technology, which
allows the QKD system to distribute key material continuously in even
the most challenging operation conditions, including temperature induced
changes in fiber lengths, passed all tests it was put through. We look
forward to more collaboration with Quantum Xchange on both technology
and business partnerships for many years to come.”
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.
About Quantum Xchange
As a provider of quantum encryption and secure communications, Quantum
Xchange gives commercial enterprises and government agencies the
ultimate defense to keep high-value data safe – today, tomorrow and in
the future. Offering the first and only quantum-secured network in the
United States, Quantum Xchange enables organizations to send infinitely
secured data over long distances using the laws of quantum physics.
Leveraging the proven secure Quantum Key Distribution
(QKD) method and its own exclusive Trusted Node technology for unlimited
point-to-point distances, Phio by Quantum Xchange addresses the
shortcomings inherent with modern-day encryption: the ability for keys
to be intercepted, corrupted or exposed during transmission, and the
imminent threat of quantum computers. To learn more about the future of
security realized today, visit QuantumXC.com or
