This folder contains all the data and code used in the work. See individual `Read_me.txt' file in each subfolder for more description, and check the comments in each matlab code file for clarity. In the folder `r_c___probability_data', the Gaussian distribution data aren't saved (Fig.12 and inset of Fig.3), and one can reproduce the results ready by running `rc_gaussian_prob_distribution_check'. In the other subfolder `monitored_free_fermion_data', the code `Kitaev_chain.m' can reproduce simulation of your choice of parameters. Feel free to email the main author if confused!
