Quantum cryptography consists of using the properties of quantum physics to establish cryptography protocols that achieve levels of security that are proven or conjectured not achievable using only classical phenomena. An important example of quantum cryptography is the quantum distribution of keys, which we have been able to present in this reflection, more in relation to the RSA protocol, by proposing to increase its security by using these principles of quantum cryptography for the distribution of the private key
