2-3 people group projects. You may choose to do a literature review project or (more exciting) original research. For literature review, you’d read a few papers around a topic, understand the connection of this topic to the general field of quantum computing as well as the of various works under this topic. The final outcome would be a survey paper including interesting open problems. For research project, identify clearly a problem (e.g., designing/improving an algorithm for a specific task) and let your creativity guide you while maintaining reasonable precision! You are not requried to completely solve a problem (big congrats if you do!).
- Proposal: 1-2 pages consisting of 1) the topic, background, context, motivation; 2) brief summary of the relevant works and core papers to be studied; and 3) a goal you intend to achieve and a plan.
- Mid-term report: ~5 pages. After more reading and group discussion, your mid-term report should have a polished and expanded version of your proposal. You also need to demonstrate the progress you’ve made since the proposal.
- Oral presentation: Each group will have about 20mins to present your project, demonstrating both breath and depth: you should aim for a clear introdution of your topic with sufficient background and motivation that would interest the audience; and then you may choose to explain 1-2 techincal ideas in a little detail. Every group member needs to participate, and your group will be graded by other fellow students. You may give your the presentaion on board or with slides.
- Final report: ~10 pages. This should resemble a real research paper: a short abstract; 2) an introduction that motivates the topic/problem and gives an overview of the entire paper; 3) details including proper preliminary materials (e.g., notations & defintions), explaning some main technical results; and finally 4) further discussion and open questions.
- Report format: single-column, single-space (between lines) format on letter-size paper. LaTeX and BibTeX are highly recommended. Here is a simple [TeX PDF] template. You may follow a suitable 2017 ACM Article Template (e.g., ACM Small format). Many LaTeX and MS word templates are availabe there.
- Week 1 & 2: forming groups.
- Week 3 & 4: meeting and discussing project ideas.
- April 27: proposal due.
- May 18: mid-term report due. Extended till Monday, May 22!
- Week 10: in-class presentations.
- June 15: final report due.
