What are the key differences between quantum cryptography and classical cryptography?

What are the key differences between quantum cryptography and classical cryptography?

Quantum cryptography uses quantum mechanics to secure data, while classical cryptography relies on mathematical algorithms.

Can you explain how quantum key distribution works?

Sure! Quantum key distribution (QKD) allows two parties to generate a shared secret key using quantum states, ensuring security.

What are the advantages of using quantum cryptography?

The main advantages include enhanced security against eavesdropping and the ability to detect any interception of the key.

Are there any practical applications of quantum cryptography today?

Yes, quantum cryptography is being used in secure communications for banks, government agencies, and research institutions.

How does classical cryptography compare in terms of security?

Classical cryptography can be vulnerable to advances in computing power, such as quantum computers, which can break many algorithms.
