    "abstract": "We investigate the entanglement properties of a finite size 1+1 dimensional\nIsing spin chain, and show how these properties scale and can be utilized to\nreconstruct the ground state wave function. Even at the critical point, few\nterms in a Schmidt decomposition contribute to the exact ground state, and to\nphysical properties such as the entropy. Nevertheless the entanglement here is\nprominent due to the lower-lying states in the Schmidt decomposition.",
