Simulation and visualization of ternary unitary networks, implemented in Python/NumPy

Ternary unitary quantum lattice models in 2 + 1 dimensions

Python implementation accompanying the manuscript arXiv:2206.01499.

For a demonstration of the code, run python3 equal_time_correlation.py, which computes an equal-time correlation function and visualizes the required tensor network contraction:
