One of the great potential applications of quantum mechanics is quantum cryptography. According to physicists, quantum cryptography is a safer method for transmitting the desired information, as it uses the logic of quantum mechanics, unlike classical cryptography. What matters in quantum cryptography is quantum keying. For this, basically, two quantum algorithms or protocols have been created. The first of these is the BB84 protocol, which is still used today. This method was developed by Charles Bennett and Gilles Brassard in 1984. This protocol takes advantage of the polarization states of photons. Let's start to explain the protocol through familiar names. Let Alice want to send the requested information, for example, 11010011, to the recipient Bob. Let Eve, our third character, be the person who captures the quantum information Alice sent before it reaches Bob. Alice will transmit 11010011 information, which is made up of photons, to Bob via fiber optic cables. | Let the an...
