Quantum Secure Direct Communication using Entanglement and Super Dense Coding

摘要

This paper introduces a new quantum protocol for secure direct communication.This protocol is based on Entanglement and Super-Dense coding. In this paper wepresent some basic definitions of entanglement in quantum mechanics, presenthow to use the maximally entangled states known as Bell States, and super densecoding technique to achieve secure direct message communication. Finally, wewill apply some error models that could affect the transmission of the quantumdata on the quantum channels, and how to treat these errors and acquire a safetransmission of the data.
