Abstract

We quantify multiparticle quantum entanglement in a system of N twolevel atoms interacting with a squeezed vacuum state of the electromagnetic field We calculate the amount of quantum entanglement present among one hundred such twolevel 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 twolevel atoms are made up of all possible bipartite correlations among the N atoms
