Abstract
We study the entanglement entropy arising from coherent states and one -particle states. We show that it is possible to define a finite entan glement entropy by subtracting the vacuum entropy from that of the con sidered states, when the unobserved region is the same. (C) 1996 Acade mic Press, Inc.
