What is quantum cryptography and how does it work?

Quantum cryptography is a method of secure communication that uses the principles of quantum mechanics. It allows two parties to exchange information securely, ensuring that any attempt at eavesdropping can be detected.

What makes it more secure than classical cryptography?

Quantum cryptography leverages the uncertainty principle of quantum mechanics, meaning that any measurement of a quantum system disturbs it. This allows the communicating parties to detect eavesdroppers.

Can you explain the concept of quantum key distribution?

Sure! Quantum Key Distribution (QKD) is a technique used in quantum cryptography to securely share encryption keys between two parties. It ensures that any interception of the key can be detected.

Are there any real-world applications of quantum cryptography?

Yes, quantum cryptography is being explored for secure communications in various fields, including banking, government, and military applications.
