Experimental Realization of Quantum Cryptography by Arduino

Abstract

This paper is concerned with the experimental realization of an Arduino-based quantum cryptography system, in which a setup of five laser diodes is constructed in the transmitter that randomly emits photons to encode information consisting of a sequence of "0" and "1" bits. The receiver contains five photoresistor sensors that detect the presence or absence of light as well as determine the intensity of the light. Laser light is used to securely transmit data, such as text or numbers, in this technology.
