This study aims to answer directly to four questions relating to knowledge of what Quantum Cryptography is. The text is developed through a historical overview of the encryption of messages, reaching asymmetric encryption, a solution to the problem of production and distribution of keys. Afterwards, inserted in a quantum scope, it defines and exemplifies protocols of quantum cryptography, showing, in conclusion, the responses required.
