Abstract:
Quantum Key Distribution (QKD) has come a long way since the advent of
the BB84 protocol and an integral step in this development has been that
of Measurement Device Independence (MDI). As such I have attempted to
track this development in Discrete Variable-Quantum Key Distribution (DV-
QKD) by studying theoretically the important aspects that make up a QKD
type setup. I then move on to explain one of the more recently developed
protocols in light of the physics involved that transmits and generates the
signal state as well as how it is interpreted for it to be considered as one of
the Bell States, a necessity for MDI type protocols.
