The principle behind quantum encryption revolves around leveraging the laws of quantum mechanics to achieve secure communication. It utilizes quantum bits, or qubits, which can exist in multiple states simultaneously. This allows for the detection of eavesdropping, as observing a quantum system inevitably alters it. Quantum Key Distribution (QKD) is a common method of implementing quantum encryption, ensuring that only authorized users can access the shared encryption keys. As a result, quantum encryption offers enhanced security compared to traditional encryption methods.
