What is Quantum cryptography?

Quantum cryptography is an encryption approach that leverages quantum physics' naturally occurring features to secure and transmit data in an unhackable manner.

Cryptography is the technique of encrypting and safeguarding data such that it can only be decrypted by someone who has the correct secret key. Quantum cryptography is distinct from standard cryptographic systems in that it bases its security model on physics rather than mathematics.

Quantum cryptography is a system that is entirely safe against being hacked without the message sender or recipient being aware of it. That is, copying or seeing data encoded in a quantum state without alerting the transmitter or receiver is impossible. Quantum cryptography should be impenetrable to those who use quantum computing.

Quantum encryption sends data across fiber optic wire using individual photons, which are light particles. Binary bits are represented by photons. Quantum physics is used to ensure the system's security.

At the same time, particles can exist in multiple locations or states; a quantum feature cannot be observed without causing it to change or be disturbed; and complete particles cannot be replicated.

Because of these features, measuring the quantum state of any system without upsetting it is impossible.

Photons are employed in quantum cryptography because they have all of the required properties: They have well-understood behaviour and serve as data carriers in optical fiber connections. Quantum key distribution (QKD), which provides a secure technique for key exchange, is now one of the most well-known examples of quantum cryptography.
