| Abstract: | We present two schemes for concentrating unknown nonmaximally
entangled Greenberger-Horme-Zeilinger (GHZ) or W class states. The first scheme for concentrating
the nonmaximally entangled GHZ state is based on linear optical
devices. The second scheme for concentrating the W class states
can be applied to a wide variety of atomic state. Both of our
schemes are not postselection ones and are within the current technologies. |
