Quantum Foundations

States, measurement, and the rules of quantum mechanics

beginner~45 min6 lessons

Start here. Learn what a quantum state is, how measurement works, and why quantum mechanics behaves differently from everything you already know. These six lessons build the vocabulary and intuition that every later module depends on.

Quantum Brain

See prerequisite ideas, theorem links, simulator paths, and hardware links for this module.

What you will learn
  • Describe what a quantum state is and how it differs from a classical state
  • Explain why measurement changes a quantum system
  • Read and write simple quantum state notation
