# ECE 498EC Fall 2020

**Course Description** – This course introduces the basic concepts and principles underlying quantum computing and quantum communication theory. Roughly 33% of the course will be devoted to teaching the necessary mathematical tools and principles of quantum information processing, 33% to quantum computation and communication, and 33% to entanglement theory. The specific topics covered in this course are chosen to reflect areas of high interest within the research community over the past two decades. The student will be expected to perform detailed mathematical calculations and construct proofs. By the end of the semester, the student should be equipped with enough background and technical skill set to begin participating in quantum information research.

**Format and Schedule **– All course activities will take place through a Microsoft Teams workspace. This includes video lectures, notes, homework, and discussions. Live lectures will be given T/R 3:00PM – 4:20PM, and these will be recorded for future viewing. A 90-minute virtual office hours will be held 1:30PM-3:00PM every Friday.

**Prerequisites** – Linear algebra required; quantum mechanics, and probability/statistics recommended.

**Textbook** – The primary course material will be lecture notes generated by the instructor. A suggested supplemental textbook is *Quantum Computation and Quantum Information* by M.A. Nielsen and I.L. Chuang.

**Grading **– Grades will be based on 50% homework, 25% Midterm, and 25% Final.

**Four Credit Option **– This course can be taken for four credits. The additional credit requires writing a review paper on some quantum information research article. The paper should be at least six pages in length and provide a background discussion of the paper, a derivation of the major results, and a conclusion describing future areas of research. All papers to be reviewed must be pre-approved by the instructor, and suggested papers can also be provided.
