Whispering Using Quantum

[ABSTRACT]

Information security is more important than ever in modern societies, fromnationalsecurity to personal bank account, from security of auto-driving to personal medical data. As quantum computing is developing fast, the day when existing encryption become useless is coming near. Aainst this background, quantum communication appears as a solution to this threat. One well-known quantum communication is quantum key distribution (QKD), which agrees a random key between distant users, and then these keys are used in classical encryption, for instance the one-time-pad scheme. Another quantum communication, quantum secure direct communication (QSDC) is to transmit information directly using quantum states. QSDC was proposed by the speaker in 2000, and is undergoing rapid development in recent years. Its basic principle is to use the principles of quantum mechanics to perceive eavesdropping and design protocols that prevent eavesdroppers from obtaining the information. It is whispering using the quantum world principle. QSDC is whispering and thus is stealthy. It is compatible with existing internet, and hence flexible in application. In this talk, we will talk briefly the QSC principle and recent development.

在现代社会，从国家安全到个人银行账户，从自动驾驶到个人医疗数据，信息安全比以往任何时候都更加重要。随着量子计算的快速发展，现有加密变得无用的那一天即将到来。在这种背景下，量子通信作为一种解决方案出现了。一个众所周知的量子通信是量子密钥分配(QKD)，它在遥远的用户之间同意一个随机密钥，然后这些密钥被用于经典加密，例如一次一密方案。另一种量子通信，量子安全直接通信(QSDC)是利用量子态直接传输信息。QSDC由演讲者于2000年提出，近年来发展迅速。其基本原理是利用量子力学原理感知窃听，设计防止窃听者获取信息的协议。它在用量子世界原理窃窃私语。QSDC是耳语，因此是秘密的。它与现有的互联网兼容，因此应用灵活。在本次讲座中，我们将简要介绍QSC原理及其最新发展。
