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

Alice In Quantumland now connects chapters, review, labs, and projects into one progression from first qubit to applied quantum systems.
14 hours
Gates, Entanglement, and Circuits
Move from one-qubit states to reversible operations, tensor products, Bell states, and circuit diagrams.
18 hours
Interference and Algorithms
A serious route into Deutsch-Jozsa, Grover search, phase kickback, and the limits of algorithmic claims.
16 hours
Quantum Software Practice
Applied practice with circuit construction, simulator checks, noise intuition, and reproducible notebooks.
Available chapters
The current release focuses on the single-qubit foundations needed by later chapters.
