Zusammenfassung: | At first, the ability of pure states as an entanglement catalysts for transformation between 2 × 2-dimensional mixed states is discussed. Necessary and sufficient conditions for the transformation between 2 × 2-dimensional rank 2 mixed states by entanglement-assisted LOCC operations (ELOCC) are then presented. In addition, the method to construct an entanglement catalyst for transformation between 2 × 2-dimensional rank 2 mixed states is illustrated by an example. |
