Quantum Communication

TL;DR

Quantum communication enables the transfer of unknown quantum states over distances, overcoming the no-cloning theorem that restricts classical copying methods.

Contribution

This paper discusses the fundamental principles and challenges of quantum communication, highlighting its distinction from classical communication.

Findings

Quantum states can be transferred over distances using quantum channels.

The no-cloning theorem prevents copying unknown quantum states classically.

Quantum communication has potential for secure information transfer.

Abstract

Quantum Communication is the art of transferring an unknown quantum state from one location, Alice, to a distant one, Bob. This is a non-trivial task because of the quantum no-cloning theorem which prevents one from merely using only classical means.
