Abstract

This upload contains necessary scripts and notebooks to reproduce the results of the manuscript "Time Evolution of Uniform Sequential Circuits". The logs.tar.gz and logs_envfit.tar.gz archives contain trained l-USC ansätze or environment fits with the layered structure. The attached python scripts allow one to run all the training protocols used in the paper: 1. get_exact.py -- obtain quasi-exact solution using iTEBD time-evolution of iMPS; 2. simulate_exactenv.py -- time-evolve the l-USC wave function with exact environments; 3. env_fitting_test.py -- approximation of exact environment with the layered decomposition; 4. compute_ent_entropy.py and compute_ent_entropy_exact.py -- post-computes entanglement entropy of either iMPS or l-USC ansatz; The quasi-exact rho_1024_exact_g_1.000.npy / Sz_1024_exact_g_1.000.npy files are necessary for the plotting procedure, but they are also generated by the get_exact.py script. The Bs_1024_exact_g_1.000.npy file is the quasi-exact iMPS used in this work. It has to be provided to the compute_ent_entropy_exact.py and simulate_exactenv.py scripts.
