Abstract

In this paper, a method for computing entanglement of electrons in atoms and molecules is described. The importance of entanglement computation for Quantum Computers and for Biology is highlighted and the existing models' pros and cons are illustrated. A description of the algorithms follows, with some considerations about the execution times and how they scale increasing the system's Hilbert space dimension.
