In quantum cryptography, quantum mechanical properties are applied in the performance of cryptographic tasks. A well-known method is Quantum Key Distribution (QKD), which offers an information-theoretically secure solution to the key exchange problem. Despite its security advantages, quantum cryptography has been functionally impractical due to its limited transmission distance. Terra Quantum is developing and implementing a quantum cryptography protocol which allows high speed QKD distribution over far greater distances than previously possible.
