Whispering Using Quantum

[ABSTRACT]

Information security is more important than ever in modern societies, from national security 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.

在現代社會，從國家安全到個人銀行賬戶，從自動駕駛到個人醫療數據，信息安全比以往任何時候都更加重要。隨著量子計算的快速發展，現有加密變得無用的那一天即將到來。在這種背景下，量子通信作為一種解決方案出現了。一個眾所周知的量子通信是量子密鑰分配(QKD)，它在遙遠的用戶之間同意一個隨機密鑰，然后這些密鑰被用于經典加密，例如一次一密方案。另一種量子通信，量子安全直接通信(QSDC)是利用量子態直接傳輸信息。QSDC由演講者于2000年提出，近年來發展迅速。其基本原理是利用量子力學原理感知竊聽，設計防止竊聽者獲取信息的協議。它在用量子世界原理竊竊私語。QSDC是耳語，因此是秘密的。它與現有的互聯網兼容，因此應用靈活。在本次講座中，我們將簡要介紹QSC原理及其最新發展。
