What are the advantages of quantum cryptography?

Quantum cryptography offers enhanced security through the principles of quantum mechanics, making it nearly impossible to intercept without detection.

How does it ensure security?

It uses quantum key distribution (QKD) to create secure keys. Any attempt to eavesdrop alters the quantum state, alerting the parties involved.

Are there any real-world applications?

Yes, it's being used in secure communications for banks, government agencies, and even in some telecommunications companies.

What are the limitations of quantum cryptography?

While it's highly secure, it requires specialized equipment and infrastructure, which can be costly and complex to implement.

Is it better than classical cryptography?

In terms of security, yes, but classical cryptography is still widely used due to its established infrastructure and lower costs.
