%0 Journal Article %D 2002 %T Asymptotic entanglement capacity of the Ising and anisotropic Heisenberg interactions %A Andrew M. Childs %A D. W. Leung %A F. Verstraete %A G. Vidal %X We compute the asymptotic entanglement capacity of the Ising interaction ZZ, the anisotropic Heisenberg interaction XX + YY, and more generally, any two-qubit Hamiltonian with canonical form K = a XX + b YY. We also describe an entanglement assisted classical communication protocol using the Hamiltonian K with rate equal to the asymptotic entanglement capacity. %8 2002/07/10 %G eng %U http://arxiv.org/abs/quant-ph/0207052v2 %!
