  We quantify multiparticle quantum entanglement in a system of N two-level
atoms interacting with a squeezed vacuum state of the electromagnetic field. We
calculate the amount of quantum entanglement present among one hundred such
two-level atoms and also show the variation of that entanglement with the
radiation field parameter. We show the continuous variation of the amount of
quantum entanglement as we continuously increase the number of atoms from N=2
to N=100. We also discuss that the multiparticle correlations among the N
two-level atoms are made up of all possible bipartite correlations among the N
atoms.
