Quantum cryptography

Quantum cryptography definition

An encryption method that uses quantum mechanics’ properties to transmit data in a way that cannot be hacked. More precisely, it is impossible to interact with data in transfer (view or copy it) without alerting the sender or receiver. The main difference between quantum cryptography and traditional cryptography is that the former relies on physics, not mathematics, as the basis of its security model.

Quantum cryptography advantages

  • Has the potential to encrypt data even after traditional cryptography methods become unsecure.
  • Needs fewer resources, easy to use.
  • Virtually unhackable.
