libCreme: An optimization library for evaluating convex-roof entanglement measures

This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018) Abstract We present the software library libCreme which we have previously used to successfully calculate convex-roof entanglement measures of mixed quantum states appearing in realistic physical systems. Evaluating the amount of entanglement in such states is in general a non-trivial task requiring to solve a highly non-linear complex optimization problem. The algorithms provided here are able to achieve to do this for a large and important class of entanglement measures. The library is mostly writte...
