PPT-indistinguishable states via SDP

Python script that implements the linear program used in the papers:

[Cos12] A. Cosentino, PPT-indistinguishable states via semidefinite programming. arXiv:1205.1031

[CR13] A. Cosentino and V. Russo, Small sets of locally indistinguishable orthogonal maximally entangled states. arXiv:1307.3232

See Theorem 5 in [Cos12] to understand why the SDP can be written as a linear program.

Tested with Python 2.7.3.

Requires:

Usage

In ppt_indist.py modify the parameter k and d and run it with the following command:

python ppt_indist.py
