A numerical implementation of the genuine multiparticle negativity - a genuine multiparticle entanglement monotone

=== gmn

Python package for quantifying and bounding genuine multiparticle entanglement based on the genuine multiparticle negativity.

GMNTOOLS is a free software package quantifying and bounding genuine multiparticle entanglement based on the Python programming language. It can be used with the interactive Python interpreter, on the command line by executing Python scripts, or integrated in other software via Python extension modules. Its main purpose is to make the quantification of genuine multiparticle entanglement easy for Python beginners and provide a good basis for experts.

Installation

Required and optional software

The package requires version 2.7 or 3.x of Python, and is built from source, so the header files and libraries for Python must be installed, as well as the core binaries.

The installation requires the Python convex optimization package CVXOPT as well as Numpy and Scipy.

The following software libraries are optional.

• DSDP5.8 <www-unix.mcs.anl.gov/DSDP> is a semidefinite programming solver.

Installation procedure

GMNTOOLS can be installed globally by writing:

python setup.py install

It can also be installed locally by typing:

python setup.py install --user

To test that the installation was successful, go to the test directory and run the test module provided

 cd examples/test
 python test_gmn.py

If Python does not issue an error message, installation was successful.
