Disclaimer: This post was written when Quantum Xchange was focused on building and selling the first quantum network in the U.S.
We have since pivoted our business and product offering, with the invention of Phio Trusted Xchange (TX), a first-of-its-kind quantum-safe, out-of-band key delivery system. While our technology offering can support QKD deployments, we are not a quantum communications provider or reseller. Our quantum-safe key exchange supports quantum keys generated from any source(QRNG or QKD) protected by any method (all PQC key encapsulation algorithms).
Quantum Xchange Raises $10 Million, Launches Quantum Key Distribution Service

SecurityWeek, Kevin Townsend
Newton, MA-based start-up Quantum Xchange has announced $10 Million Series A funding from New Technology Ventures, and the launch of the first commercial quantum key distribution (QKD) service in the U.S. The funding will support the deployment of a fiber network serving the Northeast Corridor from Washington D.C. to Boston, connecting the financial markets on Wall Street with back office operations in New Jersey.
The business premise is simple. The budding arrival of quantum computers will make current strong public key encryption immensely weak. Where current computing power would take too long or too many computers to make factoring large numbers feasible, one quantum computer could factor current public key lengths in a matter of minutes. Public key encryption will not provide security against quantum computers.
