Chapter 1
AvailableQubit
State vectors, amplitudes, and computational-basis measurement
Establish the notation and probability model used by every later chapter.

Editorial quantum foundations
Alice In Quantumland
A story-led introduction to quantum computing, built around precise explanations, mathematical reasoning, and carefully designed exercises.
Narrative scenes provide intuition, but every analogy is eventually connected to the formal quantum model.
Thesis
A course about the model, not the mystique
The first three chapters build the single-qubit model with careful distinctions: state vectors are not outcomes, amplitudes are not probabilities, and measurement depends on the chosen basis.
Current release
Available chapters
The current release focuses on the single-qubit foundations needed by later chapters.
Chapter 2
AvailableSuperposition
Coherence, relative phase, and interference
Show how phase makes a quantum state more than a list of outcome probabilities.
26 minIntroductory
Chapter 3
AvailableMeasurement
Basis, Born rule, and post-measurement state
Clarify what a measurement returns, what it changes, and why the basis matters.

Method
Learning methodology
Each chapter alternates between a restrained scene, formal notation, worked examples, visual checks, and short quizzes that test conceptual boundaries.
Narrative scene
Each chapter opens with a short scene that frames the idea without replacing the formal definition.
Concept clarification
Key concepts are stated precisely, with careful contrast against common classical intuitions.
Mathematical form
Notation is introduced gradually, with emphasis on what each symbol means operationally.
Check for understanding
Short quizzes test conceptual distinctions, not memorized slogans.
Progression
Course progression
Qubit -> Superposition -> Measurement -> Gates -> Entanglement -> Circuits -> Interference -> Algorithms
Begin with the smallest complete quantum system
Chapter 1 introduces the two-dimensional state space that later gates, interference, and circuits act on.
