Understanding Quantum Computers (Keio University)

This is Keio University’s popular introduction to quantum computing, delivered on the FutureLearn platform and taught by Rodney Van Meter, of Keio’s Faculty of Environment and Information Studies. Van Meter studied at Caltech, USC, and Keio and has worked on quantum computing since 2003, with a particular focus on quantum networking and computer architecture. The course is free to take, with an optional paid certificate.

The course is designed to be broadly accessible: it explains the motivation for building quantum computers, walks through the important principles of quantum computing, looks at some of the key quantum algorithms, and finishes with a brief survey of quantum computing hardware and the budding quantum information technology industry. Key concepts are explained graphically and with minimal mathematics, though the course is upfront that some genuinely deep thinking is required to follow the ideas.

Who is this for?

Curious newcomers - students, professionals, and lifelong learners - who want a credible, university-led introduction without heavy mathematics. It is well suited to people deciding whether to study the subject more seriously, and to those who want the conceptual landscape before diving into hands-on programming courses.

Prerequisites

None beyond curiosity and a willingness to think carefully. No programming, physics, or advanced mathematics background is assumed; the concepts are presented graphically with minimal formal notation.
