Quantum Cryptographic Techniques

Cryptography is the technique of scrambling plain text, i.e., encrypting data so that only those with the appropriate “key” can read it. By extension, quantum cryptography encrypts data and transmits it in an unhackable manner using quantum mechanics principles. The complexity of quantum cryptography [1] lies in the ideologies of quantum mechanics, which is given as follows: The particles that make up the space are intrinsically insecure, and they can exist in multiple places or states at once. In one of two quantum states, photons are generated at random. It is possible to clone some quantum qualities of a particle, but not the complete particle. It is impossible to measure and analyze a quantum property without disturbing or changing it.
