Abstract
We quantify various possible entanglement measures for the four particles GHZ entangled state that has been produced experimentally [C. Sackett et al, Nature 404, 256-259 (2000)].
arXiv commentLatex style, 5 pages, nofigures. This paper was written around April 2000 soon after the experimental production of four-ionic GHZ state
