“Quantum cryptography uses photons and physics to generate cryptographic keys” What is quantum cryptography?

Quantum cryptography is NOT a new algorithm to encrypt and decrypt data.

For example, text that is encrypted using AES encryption with key .

A public key is used to encrypt data whereas a private key is used to decrypt that data.
