Ground state entanglement in quantum spin chains
J. I. Latorre, E. Rico, G. Vidal
A microscopic calculation of ground state entanglement for the XY and Heisenberg models shows the emergence of universal scaling behavior at quantum phase transitions. Entanglement…

Reversible simulation of bipartite product Hamiltonians
Andrew M. Childs, Debbie W. Leung, Guifre Vidal
Consider two quantum systems A and B interacting according to a product Hamiltonian H = H_A x H_B. We show that any two such Hamiltonians can be used to simulate each other reversi…
