Quantum technology (i.e., modern technology based on quantum mechanics) is a subject of national importance. Countries in the world are racing to build quantum computers. The aim of this module is to expose you to this fascinating area, as well as applications of quantum technology to computing and communication. Students in Communications and Signal Processing, as well as other branches of EEE, with usual background on linear algebra and probability theory will be able to learn this module without mathematical difficulty. The module will be jointly delivered by the EEE and Physics Departments.

By the end of this module you will be able to (1) evaluate quantum technology for information engineering, (2) assess quantum computing and quantum communication systems, (3) develop speedy computation and secure communication with quantum computing, (4) analyse impacts of quantum computing on the security of modern cryptography, and (5) design quantum-safe cryptography using classical approaches.

Topics include quantum bits, quantum gates, quantum computing, quantum communications, quantum attacks to classical cryptography, lattice-based cryptography and code-based cryptography.
