Internet has become a global means of communication, turned our reality upside down. It has transformed communications, to the level that it is now our chosen standard of communication. Although there are many ways to protect information from undesired access, Quantum cryptography can be used to unconditionally secure data communications by applying the laws of quantum physics which overcomes the drawbacks of traditional classical cryptography, which depends on mathematical methods to limit attacks such as eavesdroppers. Quantum cryptography is considered to be a future replica of classical cryptography. In this survey paper, we will discuss about various protocols of cryptography. Also discussing about their vulnerabilities.

Discussion on quantum cryptography is largely focused on quantum key distribution. This leads to the terms occasionally being used interchangeably. However, quantum cryptography is a wide field of study encompassing more than just key distribution. This paper surveys many areas of research in quantum cryptography and how they have developed both theoretically and experimentally. This serves as both a summary of the landscape and provides a basis to construct a trajectory of the future in the field. The paper concludes that many of these areas of study suffer similar drawbacks when being realized and that some require more theoretical advancement. In response to these drawbacks, device independent protocols have gained traction in the field.
