Reviews

Prepare to spend a lot more hours to study if you really want to understand the lectures fully.

Good course for beginners to understand the basic concepts on Quantum theory and its applications in theory.

This is an advanced topic taught by an expert in the field. I would love to have materials to read outside of the course.

This course helps who wants to begin learning quantum information.

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.
