Quantum Cryptography

The effectiveness of any cryptographic system relies on the privacy and strength of its secret keys. Considering the fact that modern-day cryptographic primitives are based on the complexity of one-way mathematical problems on classical computers, the advent of a universal quantum computer threatens its existence.

Quantum Key Distribution, as a measure against those risks, is the most mature branch of quantum communications. This technology generates encryption keys under the nose of an eavesdropper between two remote parties with information-theoretic security guaranteed by quantum principles like No cloning theorem, Heisenberg uncertainty principles, etc.

Utilization of Quantum Random Number Generators in cryptographic systems for obtaining secret keys gives us a higher degree of entropy and thus a higher level of security. As they are based on the inherent randomness of nature, they can provide us with private and uniformly distributed random numbers at high speed.
