What are some examples of quantum cryptography?

Quantum cryptography uses principles of quantum mechanics to secure communication. One famous example is Quantum Key Distribution (QKD), which allows two parties to generate a shared, secret random key.

How does Quantum Key Distribution work?

QKD works by sending quantum bits (qubits) over a communication channel. If an eavesdropper tries to intercept the qubits, the quantum state changes, alerting the parties involved.

Are there real-world applications of quantum cryptography?

Yes, companies like ID Quantique and Toshiba have implemented QKD in secure communication networks, especially in banking and government sectors.

What are the advantages of using quantum cryptography?

The main advantages include enhanced security against eavesdropping and the ability to detect any interception attempts, making it more secure than classical methods.
