What is quantum encryption and how does it work?

Quantum encryption is a method of securing data using the principles of quantum mechanics. It allows for the creation of secure communication channels that are theoretically immune to eavesdropping.

What makes quantum encryption more secure than classical encryption?

Quantum encryption leverages the uncertainty principle, meaning any attempt to measure the quantum state of the data will disturb it, alerting the sender and receiver to potential eavesdropping.

Can you explain how quantum key distribution (QKD) works?

Sure! QKD uses quantum bits (qubits) to generate a shared, secret key between two parties. If an eavesdropper tries to intercept the qubits, the key will be altered, indicating a breach.

Are there any real-world applications of quantum encryption?

Yes, quantum encryption is being explored for secure communications in finance, government, and military applications, where data security is critical.
