One qubit as a Universal Approximant

In this repository one can find all the code related to the paper One qubit as a Universal Approximant, arXiv:2102.04032

• The files main*.py summarize all the code needed for performing optimizations as explained in the paper.
• The inner engine of the simulations is written in ApproximantNN.py
• The file chi2.py corresponds to a code for painting final results on $\chi^2$
• The file painter_experimental.py paints all the different approximations of different functions
• All results are stored in the results folder, and summary.csv is an index for them
