Get an introduction to the key concepts of quantum computing
In this course, we will discuss the motivation for building quantum computers, cover the important principles in quantum computing, and take a look at some of the important quantum computing algorithms.
We will finish with a brief look at quantum computing hardware and the budding quantum information technology industry.
Key concepts will be explained graphically, with minimal mathematics but some deep thinking required.

Who is the course for?


Anyone interested in quantum computing at the “popular science” level.
High school students, college students, and computer professionals interested in developing a qualitative understanding of quantum computing in order to understand the future of computing will benefit.

We recommend that you be comfortable with exponents, vectors, sine waves and the basic concepts of probability. There are some equations, but we have endeavored to keep them as few and clear as possible.

While the mathematics is not too hard, some concepts will be new to most learners, and require some mental stretching. Be prepared to exercise your brain!

Who will you learn with?

Rodney Van Meter studied at Caltech, USC, and Keio. He has been working on quantum computing since 2003. He is the author of the book “Quantum Networking” (Wiley-ISTE, 2014).

Takahiko Satoh studied at Keio and U.Tokyo. His research field is quantum computing, particularly quantum computer architecture and quantum network architecture.
