Quantum Cryptography: A Brief Overview

Abstract

As countries strive to develop quantum computers, classical cryptography will be threatened by quantum algorithms. Countries are thinking of and building the next generation of cryptography to resist the threats from the quantum computer. This article provides a brief overview of the innovations and applications of quantum cryptography. In addition, the readers can learn some important quantum cryptography protocols, which can be used for further self-study as well as exploring this profound and interesting quantum cryptography in the future.
