Numerical method of entangled state selection in association of molecules

Abstract

We represent the economy method of separation of the entangled states of GHZ and W types which arise in the process of association of a single molecule. It makes possible to separate these types of quantum states in the simulation of real processes like the association of molecular ion of hydrogen by means of existing computers with the strictly limited memory. Numerical realization of this method is in process; we represent the semiclassical part of it, that is based on Landau-Ziner description of the association of molecules. Results of statistical processing of the row of numerical experiments are shown.
