What are some real-world examples of quantum cryptography?

Quantum cryptography is being used in various sectors. For instance, the Chinese satellite Micius has successfully demonstrated quantum key distribution (QKD) over long distances.

That's interesting! Are there any commercial applications?

Yes, companies like ID Quantique and Toshiba are providing quantum cryptography solutions for secure communications in finance and government sectors.

How secure is quantum cryptography compared to classical methods?

Quantum cryptography offers theoretically unbreakable security due to the principles of quantum mechanics, unlike classical methods which can be vulnerable to hacking.

What challenges does quantum cryptography face?

Some challenges include the high cost of technology, the need for specialized infrastructure, and the current limitations in distance for effective QKD.
