## Content

* Mathematica 7 scripts (with plots).

    * One without output need to be run to see plots, but also weights ~40x less.

    * They contain also scripts to manipulate and generate popular quantum states (for 1D quantum spin chains), including: 

        * product states,

        * Dicke states (i.e. permutation-symmetric with a fixed number of excitations),

        * Ising Transverse Field ground states, parametrized by $\Gamma$,

        * AKLT ground state.

* C++ programs.

    * It includes wavefunction examples.

* Python [Qubism in QuTiP package](http://nbviewer.ipython.org/github/qutip/qutip-notebooks/blob/master/examples/example-qubism-and-schmidt-plots.ipynb).

From user's perspective, the **Python implementation in QuTiP** is the easiest, most mature and production-ready.
