About the Course

The course provides an introduction to quantum information at a beginning graduate level. It focuses on the fundamental understanding of how information is processed with quantum systems and how the quantum properties apply to computing and communication tasks. The course begins by presenting quantum theory as the framework of information processing. Quantum systems are introduced with single and two qubits. Axioms of quantum theory such as states, dynamics, and measurements are explained as preparation, evolution, and readout of qubits. Quantum computing and quantum communication are explained. Entanglement is identified as a key resource of quantum information processing. Manipulation and quantification of entangled states are provided.  Quantum information processing opens an avenue to new information technologies beyond the current limitations but, more importantly, provides an approach to understanding information processing at the most fundamental level. What is desired is to find how Nature performs information processing with the quantum and classical systems. The ultimate power of Nature in computing and communication may be found and understood. The course provides a modest step to learn quantum information about how physical systems can be manipulated by the laws of quantum mechanics, how powerful they are in practical applications, and how the fundamental results make quantum advantages....

Challenging quizzes and final exam; understanding solutions to problems boosts understanding of the topic. Many topics clearly, albeit rapidly, covered.Review with self-reading contextualizes material

The course was challenging as an Introductory course. I had to read through books and solve problems before taking the test, as the lectures and assignments required a fair bit of formalization.

The positive aspects of this course is the technical depth. The course covers a range of key topics in quantum information from quantum gates, entanglement, quantum channels, and measurements. The materials fit a first semester graduate course on the topic.

However, I believe this course is poorly structured. First of all, the lecture videos are very jargon heavy and often new terms and concepts are introduced without any definition. The instructor is often unclear about a step and hand waves details when showing a proof or explanation. There is little to no time dedicated to motivation for certain topics. I found the videos only useful when used as a secondary source with a textbook such as “Quantum Computation and Quantum Information” by Nielsen and Chuang. (Which by the way is something I found on my own as there is no additional resources recommended by the course).

The assignments and the one exam are all multiple choice based and no explanation is given on the correct answer. While the problems are interesting, the majority are geared towards determining if you’ve watched the videos and recall certain statements or steps. Very rarely does it synthesize multiple topics together to gauge a deeper understanding of the concepts. Overall, each assignment can be completed in at most half an hour.

Overall my recommendation is to use the topics selected by the instructor as a guide to learn the topic from another source. I think that the topics are important but I do not think a student who is not already somewhat familiar with the topics will learn much from this course.

I have some engineering/physics background but no formal training on quantum information. Am trying to understand more through self-learning.

Tried this course after going through some basic quantum computing books on qubits and gates. Found this to be useful to introduce deeper topics to me and push me to work out problems to learn some of these concepts.

Would have been nicer if Dr Bae could provide some reference answers or help in the forums as I'm still not confident that my understanding of problems was correct even though I passed the quizzes.

Good material; it would be nice to have some example calculations. In some cases, the jump from general theory to concrete calculation in the exercises is a bit large.

More clarifications could be expected in some mathematical concepts and in the notations. Some answers proposed in a few exerices seem not coherent of the right answer. This can lead to misunderstandings. Moreover, we could expect a detailed correction of the exercices when the course is paid in order to better understand the correct results and how to achieve it.

The lecture on this fascinating subject of quantum information was presented with commendable technical depth. However, there is room for enhancement in the pedagogical approach adopted. A number of terms and tools were introduced without sufficient definition or context, which could potentially lead to confusion. While viewing the lectures does not directly facilitate the completion of the individual quizzes or the final examination, it does necessitate a comprehensive understanding of the subject matter. This understanding often requires the exploration of various other resources, which, although demanding, fosters a profound comprehension of the topic. Nevertheless, a stronger correlation between the lecture content and the exercises would be beneficial. The exercises themselves are far from simple, requiring a solid foundation in advanced mathematics and information theory. However, they serve as an invaluable tool in providing a thorough introduction to the field of quantum information.

The course materials were very good. The lecturer was knowledgeable though it felt like he was explaining to some professor rather than beginners like us. I had to look around at other online lectures on YouTube to understand some topics. So, be prepared to learn from sources other than this to introduce yourself to Quantum Information.
