Quantum key distribution (QKD) is a technology that enables secure communication by using the principles of quantum mechanics to generate and distribute cryptographic keys. QKD provides unconditionally secure communication, making it an essential technology for various industries such as military, finance, and health care. This paper provides an overview of QKD, including its principles, different protocols, experimental implementations, practical applications, ongoing research efforts, and future prospects. The different QKD protocols, such as BB84, E91, and SARG04, are described along with their experimental implementations using both discrete-variable and continuous-variable techniques. The practical applications of QKD, including secure communication, data privacy, and cryptography, are discussed, along with ongoing research efforts aimed at improving the speed, range, and scalability of QKD. The paper concludes with a summary of the key contributions of QKD to the field of quantum information science and its potential impact on society.
