Quantum key distribution is a catchword among industry specialist now a day.It is arising an alarming situation to all the current network security techniques. These are the basic properties of Quantum Mechanics, which makes a combination with network security. At present there are so many companies out there in market which are making progress it this fields day by day.Quantum cryptography is a very important technology now days as it is helping a lot to secure the future network communication. This particular field has gained the attention from industry as well as from academics. Here we are writing this paper to provide the general review of various fields belongs to Quantum Computing, but our main aim is to provide a brief review and analysis of recent development in the field of Quantum Key Distribution, most famous and developed field of Quantum Computing. This paper presents review of Quantum Computing including different application fields like Quantum public key cryptography, QKD, Quantum Authentication. First we discuss the basics of Quantum Cryptography then we discuss the definition of Quantum key Distribution, Various protocols of this field. Then after we discuss the opportunities in this field.

Quantum Key Distribution (QKD) is a ground-breaking solution to secure communication that uses fundamental quantum mechanics principles to allow for the exchange of cryptographic keys with provable security. BB84 and E91, two of the first and most significant QKD systems, presented two different approaches to using quantum characteristics to prevent eavesdropping and maintain confidentiality. A brief literature review of these two fundamental protocols is presented in this paper. Bennett and Brassard created the BB84 protocol in 1984. It uses polarized photons and detects interception using the uncertainty principle. On the other hand, Bell's theorem and entangled photon pairs are used in the E91 protocol, which was first presented by Ekert in 1991, to guarantee the integrity of the shared key. Each protocol's theoretical foundations, methods of implementation, and relative benefits has been explored in addition to how they have influenced contemporary quantum cryptography systems. This paper attempts to give a basic understanding of QKD and its early advancements by examining the similarities and differences between BB84 and E91.
