Quantum cryptography
What is it?
Quantum cryptography is an umbrella term used to describe technology from two separate but closely linked fields that will have sweeping effects on secure communications of the future.
Quantum computing is a method of approaching computing problems using quantum effects that solves problems that are impossible to solve using conventional computers. This involves using a ‘quantum bit’ (or qubit) that can be 0 or 1 (like a normal bit) or a combination of both simultaneously.
Quantum encryption is a new means of securing communications that uses Heisenberg’s Uncertainty Principle, which states it is impossible to measure something without changing it. This enables the sending of keys that cannot be eavesdropped upon without being destroyed.
