ABSTRACT = {Quantum Key Distribution seems very promising as it offers 
unconditional security, that’s why it is being implemented by the tech giants of the 
networking industry and government. Having quantum phenomenon as a 
backbone, QKD protocols become indecipherable. Here we have focused on the 
complexities of quantum key distribution and how this technology has contributed 
to secure key communication. This article gives an updated overview of this 
technology and can serve as a guide to get familiar with the current trends of 
quantum cryptography.},
