A path-integral quantum Monte Carlo code for simulating quantum annealing with arbitrary Ising Hamiltonians. It is written based on the 2002 Phys. Rev. B paper by Martonak, Santoro, and Tosatti entitled, 'Quantum annealing by the path-integral Monte Carlo method: The two-dimensional random Ising model' (you may find a free copy of this on arxiv.org).
There are also extensions to this paper by including System Bath coupling to capture dephasing effects as well as Wolff and Swendsen-Yang cluster updates.
This simulation package is written in Cython and requires scipy and numpy. The C files are included with the .pyx. Installation requires setuptools.
After cloning the repo, navigate to where you see setup.py and run python setup.py install, or if you're developing (or wish to uninstall later) do python setup.py develop (where you can write python setup.py develop --uninstall if you wish to remove it later).
After cloning the repo, check that you have Microsoft Visdual studio, and that you have the C builder extension installed such that your windows has the 'x86 Native Tools Command Prompt for VS XXXX'.
Open and move to the directory with setup.py and run python.exe setup.py build_ext --inplace --compiler=msvc.
See examples for general usage. Not all functions are fully tested. Expect to see a 10x-80x improvement over traditional python.
