What is quantum cryptography and how does it enhance security?

Quantum cryptography uses the principles of quantum mechanics to secure data transmission, making it nearly impossible to intercept.

How does it differ from classical cryptography?

Unlike classical cryptography, which relies on mathematical algorithms, quantum cryptography uses quantum bits (qubits) to ensure security.

Can you explain the concept of quantum key distribution?

Quantum Key Distribution (QKD) allows two parties to generate a shared, secret random key using quantum mechanics, ensuring secure communication.

What are the practical applications of quantum cryptography?

Practical applications include secure communications for banks, government agencies, and any organization needing high-level data protection.

Are there any limitations or challenges with quantum cryptography?

Yes, challenges include the need for specialized equipment, distance limitations, and the current high cost of implementation.
