Entanglement Enhancement in an XY Spin Chain

  • Received Date: December 13, 2010
  • Published Date: April 30, 2011
  • We study evolution of entanglement in an XY-type spin channel and find that the entanglement can be enhanced by the spin channel. The parameter regions of the initial states for different numbers of sites are obtained. Furthermore, we consider a common spin environment coupling to the spin chains and find that the entanglement enhancement can also be implemented only for the chains with the odd numbers of sites.
