Quantum & category theory

projects/quantum/

Training what the next quantum model receives

category theory
quantum machine learning
quantum computing
rust

This post documents recent work of mine on composability of quantum machine learning models and how different model inferfaces changes what a model later in a sequence can reproduce. It is a good deal more verbose than a paper to be easier to get into by a more general reader.
