ABSTRACT
Quantum mistake rectification code has a significant task to carry out in shielding the data from blunders coming about because of de lucidness and other quantum commotion sources. This method plays an urgent viewpoint in accomplishing quantum calculation. Quantum key dispersion utilizes singular photons for the safe transmission among transmitter and beneficiary. In the event that a photon goes in a free space, its polarization state stays unaltered, believing the air choppiness to be immaterial. However, on the off-chance that a similar photon goes in an optical fiber, its polarization state changes radically. In this exploration quantum encryption and decoding is accomplished by misusing the properties of quantum articles like photon.
