The sender sends a photon through a polarizer with randomly assigned polarizations and bit assignment
Photon uses a beam splitter that can be horizontal, vertical, or diagonal to decode or read the polarization of each photon
Receiver tells the sender the random assignments of a beam splitter for each photon in the same sequence it was sent

Data retrieval in its original form
It requires large block size
Padding is done to make the plain text divisible into blocks of fixed size
It is prone to cryptanalysis since there is a direct relationship between plain text and cipher text.

The input text is divided into two parts: one being left half and another one being right half.
Swapping of the left and right halves are performed after each round.
