Meet the First Commercial Quantum Communication Network in the United States.
Phio by Quantum Xchange secures your critical communications.
Phio leverages the fundamental properties of quantum mechanics— using photons of light, not electronic bits, to physically transfer a shared secret between two entities.
This solves the fundamental problem with modern-day encryption: the ability for keys to be intercepted, corrupted, or exposed during transmission.
The Trusted Node network system
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. The Trusted Node network system from Quantum Xchange alleviates the range 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.
Quantum Xchange Trusted Node
Go the distance
The Quantum Xchange Trusted Node is composed of two or more conventional QKD system endpoints located within a common secure housing. As long as a continuous path of Trusted Nodes links two widely separated endpoints, those endpoints can still share quantum-derived key information over this much longer path. Between consecutive nodes, key information is protected by the same quantum mechanisms as in a singular QKD system. While within a node, key information is protected by encryption with locally-generated keys and a secure boundary that prevents tampering. And since a Trusted Node can include a number of QKD endpoints, the network topologies that can be realized by the Trusted Node are essentially limitless.
Quantum Xchange has the ability to offer quantum key encryption on the first commercial QKD-as-a-Service quantum network in the United States. Separate from an enterprise’s fiber data network, customers retain absolute control and visibility over their encryption keys and mission-critical data using the Quantum Xchange fiber quantum network. Quantum keys for different clients are multiplexed over a common optical fiber to reduce the total cost of the solution.
Wondering what Quantum Key Distribution (QKD) is and some of its core benefits?
QKD uses the quantum properties of single photons to exchange bits between two locations.
QKD keys are derived from the exchanged quantum information.
Any attempt to intercept the key is detected because of a change in the quantum state. Corrupted keys are rejected.
