Foundations of Qubits
A precise beginner path from classical bits to the single-qubit model used by every later topic.
Current release
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.

Alice In Quantumland now connects chapters, review, labs, and projects into one progression from first qubit to applied quantum systems.
A precise beginner path from classical bits to the single-qubit model used by every later topic.
Move from one-qubit states to reversible operations, tensor products, Bell states, and circuit diagrams.
A serious route into Deutsch-Jozsa, Grover search, phase kickback, and the limits of algorithmic claims.
Applied practice with circuit construction, simulator checks, noise intuition, and reproducible notebooks.
The current release focuses on the single-qubit foundations needed by later chapters.
State vectors, amplitudes, and computational-basis measurement
Build the single-qubit pure-state model and learn how complex amplitudes become measurement probabilities.
Prerequisites
No formal prerequisites
Coherence, relative phase, and interference
Explain superposition as a coherent linear combination and show why phase affects later operations.
Prerequisites
Qubit
Basis, Born rule, and post-measurement state
Treat measurement as a physical, basis-dependent operation rather than passive observation.
Prerequisites
Qubit, Superposition
Unitary operations on state vectors
Study X, Z, and H as reversible linear operators on qubit states.
Prerequisites
Measurement
Correlations beyond separable states
Understand why some multi-qubit states cannot be decomposed into independent factors.
Prerequisites
Quantum Gates
Composing gates into algorithms
Read quantum circuits as ordered transformations followed by selected measurements.
Prerequisites
Entanglement
How amplitudes reinforce or cancel
Analyze constructive and destructive interference as a computational mechanism.
Prerequisites
Quantum Circuits
From principles to algorithmic advantage
Connect the course concepts to canonical algorithmic patterns and their limitations.
Prerequisites
Interference
Qubit -> Superposition -> Measurement -> Gates -> Entanglement -> Circuits -> Interference -> Algorithms
Work through chapters in order. Later chapters build on earlier ones.
