About

Most quantum computing tutorials are written by experts, for other experts. They assume comfort with linear algebra, Dirac notation, and the patience to work through a page of formalism before seeing a single picture. That's fine if you're a graduate student. It's death if you're fifteen years old and curious.

This site is for the second group. It's built on one idea: you should see a concept before you're asked to calculate with it. Every lesson leads with an interactive widget — something you can drag, click, or flip a hundred times — and the math shows up only when the picture has done its job.

What's live

The first ship covers the foundations of the qubit: classical warmup, meeting the qubit, the Bloch sphere, measurement, and the Hadamard gate. Five lessons — chosen deliberately because they chain together into the single most important pedagogical moment in quantum computing: I just made a superposition.

What's coming

Everything else on the curriculum page: the rest of single-qubit gates, multi-qubit systems and entanglement, quantum protocols (teleportation, superdense coding), algorithms (Deutsch–Jozsa, Grover, Shor), noise and error correction, and a tour of real quantum hardware. The roadmap is visible from day one; lessons will land as they're built.

Standing on shoulders

This site exists because other people already proved it was possible:

• Quantum Country by Michael Nielsen and Andy Matuschak showed that you can teach quantum computing with inline spaced repetition and learners will actually remember it.
• Quirk by Craig Gidney is still the gold standard for hands-on quantum circuit building.
• Bartosz Ciechanowski's blog is the reference for how interactive explanations should feel.
• Brilliant.org's quantum course showed the power of bite-sized, gamified lessons.

Built with

Astro, React, MDX, Three.js (via react-three-fiber), Tailwind, and KaTeX. The quantum simulator is a hand-rolled TypeScript library in src/lib/quantum/ — you can read it as a learning resource on how state vectors and gates are implemented in code. All 59 unit tests pass.

The site is open source and lives on GitHub.
