What Is Quantum Xchange?

Quantum Xchange provides a dynamic network for ultra-secure communications, unbreakable key exchange, and quantum readiness

“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
