“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

Ensuring your network architecture and communications is secure from known threats and the risks associated with advances in computing and mathematics can be a complex and daunting task, but the solution doesn’t have to be. Quantum Xchange offers quantum-resistant security solutions that are elegant in their simplicity and can be easily deployed across your crypto infrastructure today. 

Our ultra-secure, out-of-band, key distribution system is uniquely capable of making traditional keys quantum safe; can be deployed across any network media; leverages the power of all NIST PQC candidate algorithms; supports quantum keys in any format; and provides an easy onramp to QKD-level security without any distance or delivery limitations.
