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 differ from classical cryptography?

Unlike classical cryptography, which relies on mathematical algorithms, quantum cryptography uses quantum bits (qubits) to secure information, ensuring that any attempt to eavesdrop alters the data.

Are there any real-world applications of quantum cryptography?

Yes, quantum cryptography is being tested in various sectors, including banking, government communications, and secure data transmission.

What challenges does quantum cryptography face?

Some challenges include the need for specialized hardware, distance limitations for quantum key distribution, and integration with existing systems.
