Hadamard LLC

The company

Hadamard LLC publishes QuantumComputingCourses.com, an independent catalog of quantum computing courses, tutorials and reference. The product is the catalog. The company is the publisher.

Desks

Four desks do the work of the catalog: listings, teaching, reference, and the build that holds them to a check.

  • Course listings

    Catalog

    112 courses across 13 platforms, 64 of them free to take. Syllabus notes are written from the course itself. Outbound links are followed on a check, not assumed to still go where they used to.

  • Original teaching

    Tutorials

    220 tutorials with Python that has to run on every build. A snippet that raises is a failing build. Output printed under a code block is output that code actually produced.

  • Glossary, frameworks, hardware

    Reference

    241 glossary entries, 26 framework references, plus hardware notes and 34 industry case studies. This is the shelf the catalog sits on, not a blog roll.

  • Build, tests, hosting

    Engineering

    A static site, built and deployed as one piece. Snippet tests, affiliate-link checks and counted footer figures are part of that build. There is no separate CMS quietly rotting behind the pages.

Standards

  1. Tutorial code is executed on every build. scripts/test_snippets.py concatenates the code blocks in each tutorial and runs them. A tutorial whose code raises is a failing build. Snippets that need cloud hardware credentials cannot be run here, and those are the exception.
  2. Course links are followed, not assumed. scripts/check_affiliate_links.py checks every outbound course link. Providers rename and retire courses constantly. A link that still returns 200 while quietly redirecting to a marketing page is worse than one that is plainly broken.
  3. The numbers are counted from the files. Footer counts come from the content collections at build time. Nothing here says "hundreds of" anything, and no figure is rounded up to sound bigger.
  4. Where the quantum approach loses, the page says so. The variational classifier tutorial reports that logistic regression beats it, because on that data it does. A catalog that only ever reports flattering results is selling the field, not teaching it.

The full bar is on the editorial policy.

Corrections

Catching a code error, a dead course link or a wrong number is the most useful thing anyone can send. Email works best.
