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.

Available chapters

The current release focuses on the single-qubit foundations needed by later chapters.

  1. 1

    Qubit

    Available

    State vectors, amplitudes, and computational-basis measurement

    Build the single-qubit pure-state model and learn how complex amplitudes become measurement probabilities.

    Superposition

    Available

    Coherence, relative phase, and interference

    Explain superposition as a coherent linear combination and show why phase affects later operations.
