Why Quantum XC?

Quantum Xchange gives commercial enterprises and government agencies the best and last defense to keep data safe--today and in the future.

The world’s volume of data has been growing exponentially year after year, giving cyber criminals a greater opportunity to expose massive volumes of data

Cybercrime costs the U.S. economy $100 billion a year and costs the global economy $450 billion annually


During the First six months of 2017, more than 10M records were compromised or exposed every day

What Is Quantum Xchange?

Quantum XChange makes quantum-proof communication a reality for organizations today.

“Quantum Xchange recognized early that defensive quantum technologies were being largely ignored by technology heavyweights focused on the race for quantum computer supremacy… I am confident that their solution can protect organizations before we are faced with the consequences of quantum computing power.”

Dr. Whitfield Diffie, cryptography expert and Turing Award winner

How It Works

Quantum Xchange extends the typical range of Quantum Key Distribution beyond 100 KM.

Our quantum-secured network, Phio, is the first of its kind in the United States, and allows keys to be securely shared over a wide-ranging network, making large-scale Quantum Key Distribution possible and practical.
