Quantum Xchange: How Does It Work?

Developing a wide-area network to ensure the delivery of unhackable data

Quantum Xchange is the first-of-its-kind fiber optic network used solely to transmit and receive quantum cryptographic keys between entities that are securely transferring critical data. 

As such, Quantum Xchange is a first-of-its-kind nationwide quantum network beginning service in the New York metropolitan area and the US northeast corridor with expansion to the entire US.  The technology used to achieve this is Quantum Key Distribution (QKD).

While QKD systems are currently the only certified quantum-safe key systems available today, the range limitations of standard QKD makes it impractical to use over long distances.  Enter Quantum Xchange.  With an innovative Trusted Node network system, the Quantum Xchange alleviates the range of issues of standard QKD to provide practical, certifiable key management over a wide-area network that is unbreakable against quantum computing now and in the future.
