This program package helps modelling spin chains, qubit registers, etc. according to non-relativistic quantum mechanics and some novel ideas from quantum information theory.

In particular, it contains MATLAB routines for reordering qubits, for computing the reduced density matrix after removing some of the qubits, for partial transposition, etc. Most of the routines work also for qudits. It also has routines for handling GHZ states, cluster states, graph states, Dicke states, etc.
