In recent decades, various multipartite entanglement measures have been proposed by many researchers, with different characteristics.Meanwhile, Scott studied various interesting aspects of multipartite entanglement measures and he has defined a class of related multipartite entanglement measures in an obvious manner. Recently, Jafarpour et al.(Int. J. Quantum Inform. 13, 1550047 2015) have calculated the entanglement quantity of twodimensional 5-site spin system by means of Scott measure. As it was presented in their calculation Q 2 > Q 3 . In this paper, we would like to point out that in the 5-qudit system, Q 2 does not provide a stronger entanglement than Q 3 , while there is a simple relation between them.

In this article, we produce micro-macro and macro-macro states with the NOON initial state; finally, we scrutinize the effective squeezing parameter, mean photon numbers, number of input photons and number of macroscopic modes on concurrence.
