Introduction to Quantum Information (KAIST)

This course from the Korea Advanced Institute of Science and Technology (KAIST) presents quantum information at a beginning graduate level. Taught by Associate Professor Joonwoo Bae of the School of Electrical Engineering, it frames quantum theory as a framework for processing information and works carefully through how quantum properties translate into advantages for computing and communication tasks. It is free to audit on Coursera, with a paid certificate available.

The course opens by introducing quantum systems through single and two-qubit examples, then builds up the axioms of quantum theory: quantum states, operators, and measurement. From this foundation it develops the core machinery of quantum information processing, including quantum gates, quantum circuits, and algorithms. A recurring theme is entanglement as a physical resource, which is what makes effects like quantum teleportation and superdense coding possible.

Who is this for?

This is an advanced course aimed at students and professionals who want a rigorous, theory-first grounding in quantum information rather than a tools-focused programming course. While the course states no strict prerequisites, it is genuinely at a graduate level: comfort with linear algebra, probability, and basic information theory will make the material far more approachable.

Prerequisites

Linear algebra (vector spaces, inner products, eigenvalues), probability theory, and ideally some exposure to classical information theory. No programming is required, as the course focuses on the mathematical and conceptual framework rather than implementation.
