Apresentamos de maneira detalhada os quatro protocolos de distribuição de chaves que fundaram a importante área da criptografia quântica, numa linguagem acessível a alunos de graduação em Física. Começamos pelo protocolo BB84, o qual se utiliza de estados de polarização de fótons para transmitir chaves criptográficas. Em seguida, apresentamos o protocolo E91, que faz uso de singletos para gerar uma seqüência de números aleatórios. Finalizamos este artigo apresentando o protocolo BBM92 e o B92, os quais podem ser vistos como simplificações dos dois primeiros protocolos.We show in details the four quantum key distribution protocols which initiated the important field of quantum cryptography, using an accessible language for undergraduate stud...
