Learn the mathematics behind quantum computing, from complex numbers and linear algebra to qubits, quantum gates, entanglement and algorithms. Work through written explanations, equations and exercises at your own pace, using the notation you will encounter in textbooks and research papers.
Start with high-school mathematics; no previous quantum computing knowledge is required. The Mathematical Foundations chapter introduces the tools you will need. If you already know complex vector spaces, linear algebra and bra-ket notation, you can begin with Qubits and Gates.
Start with the course introduction or begin the first lesson: Complex Numbers.
