About this document
Global Entanglement in Multiparticle Systems by Daniel Orsini is a document available to read on EtoBox.
This document defines a polynomial measure of entanglement called Q that can be applied to systems of any number of spin-1/2 particles. Q is calculated for some example states including EPR-Bohm states, GHZ states, and eigenstates of the Heisenberg antiferromagnet Hamiltonian to illustrate that it quantifies global entanglement. Q is shown to be zero if and only if the state is a product state, and bounded between 0 and 1 when properly normalized.
