-This entry is a an overview of the code examples (shorter bits of demonstrative code that use the Shim library) that I have implemented. It is technical. It is assumed that this is perhaps not the first time the reader has heard of category theory. The reading will benefit greatly from basic prior knowledge of concepts like monads, functors (ofc how can we otherwise grok monads), categories. Basic knowledge of quantum computing is needed but I set the level of the text to not assume deep prior expertise. +This entry is a an overview of the code examples (shorter bits of demonstrative code that use the [[https://github.com/erikkallman/shim|Shim library]]) that I have implemented.

 What im hoping is that for someone active in category theory research, ML, or quantum computing can read this post and understand why I started writing Shim and see its value as a research tool. Please do contact me should you find this interesting and if any inaccuracies (I know quite a few in the code already) exist. Im happy to collaborate and discuss. What im hoping is that for someone active in category theory research, ML, or quantum computing can read this post and understand why I started writing Shim and see its value as a research tool.

It aims to describe quantum computation and machine learning through categorical structures, enabling composition of quantum operations and data transformations.
  
 In the repo there are three larger illustrative examples that showcase its usage. This is just a highlight of some of the categorical concepts used in Shim. For a full read, clone the git repo and run the examples that come with extensive documentation.  In the repo there are three larger illustrative examples that showcase its usage.
