Auxiliary-field quantum Monte Carlo (AFQMC) implementation of swap algorithm for measuring entanglement entropy and other QI-related quantities in interacting systems. Current version only supports Hubbard-type model but is extendable to general systems that are sign-problem-free.
To run the code, several example scripts are provided in the examples folder.
The module itself does not provide any built-in measurement functions expect for entanglement-related measures. Nevertheless, regular measurements can be performed on the script level. Example scripts on measuring spin correlation functions can be found in examples/utils folder.
