Press Release

October 24, 2018 — BOULDER, Colo.–(BUSINESS WIRE)–Quantum Xchange has selected Zayo Group Holdings, Inc. (NYSE: ZAYO) for a dark fiber solution to power the first Quantum Key Distribution (QKD) network in the U.S. The 530-mile route will extend from Boston to Washington D.C., leveraging Zayo’s existing network along the eastern corridor.

Quantum key distribution, an innovative encryption method that relies on properties of quantum mechanics, physically transfers a shared key between two entities that can be used to encrypt and decrypt messages. The properties of the photonic key prevent the transmission from being unknowingly interrupted, corrupted, cloned, or exposed. The new technology will address the shortcomings of algorithmic encryption and the imminent threat of quantum computers which could break algorithmic encryption.

Quantum Xchange plans to deploy the dedicated dark fiber to activate the initial leg of its nationwide network, connecting the financial markets on Wall Street with back office operations in New Jersey.

“With high capacity, low latency and inherent security, Zayo’s dark fiber infrastructure is ideal for the nation’s first Quantum Key Distribution network,” said Jack Waters, CTO and president of Fiber Solutions at Zayo. “We look forward to working with Quantum Xchange on this groundbreaking initiative.”
