Entanglement Increase in Higher Dimensions

Abstract

Entanglement of generalized Quasi-Bell states is studied and numerically compared with I-concurrence (Ic), D-concurrence (Dc), negativity (N) and mutual information (S A:B ) measures. We illustrate denoted measures reveal more entanglement as the generalized two-qutrit (qudit) Quasi-Bell state tend to be more complete in d×d Hilbert spaces, d∈{3 , 4}. Entanglement and correlation of two qutrit-and two qudit-Werner states are determined analytically by employing negativity and mutual information and then compared numerically.
