TY - JOUR T1 - Asymptotic entanglement capacity of the Ising and anisotropic Heisenberg interactions Y1 - 2002 A1 - Andrew M. Childs A1 - D. W. Leung A1 - F. Verstraete A1 - G. Vidal AB - 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.
