The weekly teaching schedule will be released progressively as the course unfolds...
This course is primarily designed for postgraduate students. However, senior undergraduates are also welcome. Please note that undergraduate students must obtain formal approval to enroll in postgraduate courses at CUHK. If you're an undergraduate interested in joining, ensure you complete this approval process. If you encounter any difficulties during the process, don't hesitate to reach out to the course instructor, who will be happy to assist.
Prerequisites:Ideally, this course requires the completion of its undergraduate counterpart, CSCI3350 Introduction to Quantum Computing. However, CSCI3350 was suspended for a few years and only recently reactivated (with availability likely starting next semester at the earliest). Thus, this time, the instructor is more open to considering exceptions for interested students who have not taken an undergraduate Quantum Computing course. If you encounter any enrollment issues due to this prerequisite, please feel free to contact the course instructor for assistance.
Please note, however, that undergraduate-level knowledge of linear algebra and probability theory is required and cannot be waived.
This course serves as an advanced follow-up to its undergraduate counterpart, CSCI3350 Introduction to Quantum Computing. It offers an in-depth exploration of quantum computing, with a particular focus on areas at the forefront of both academic research and (ongoing but promising) industrial implementations.
The course is structured into two parts:
Tentative topics include:
By the end of the course, students will:
There are currently four courses at CUHK similar to this one:
To help students avoid confusion and make informed decisions when planning their study scheme, I include a comparison between this course and the similar offerings:
