Learn how causes work, then learn how quantum physics changes the question. The course starts with counting objects and fair tests and climbs, one checked step at a time, to current research on quantum causal models, indefinite causal order, and quantum machine learning.

Each level is a teaching guide, not a certificate. Every lesson has a worked example, an exercise with a solution, a self-check, and a lab. A one-minute placement check suggests where to start.
The learning map shows all 80 lessons. Pick one to trace everything it builds on and everything it unlocks, then expand the map to full screen to zoom and pan.

Eleven notebooks, from coin flips to the quantum switch, show every result in the browser. Each one opens in Google Colab with one click.
Every reference was matched against arXiv, Crossref, or the publisher's page. For causal AI the course follows Elias Bareinboim's Causal Artificial Intelligence.
An interactive map of all prerequisites, and a short adaptive quiz that suggests a starting level.
Lectures, explainers, and podcast episodes for every level, including Decoding Causality.
No background is needed for Level 0, and every page stays open, so you can jump ahead or back at any time.
