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…
Simulation of quantum dynamics with quantum optical systems
E. Jané, G. Vidal, W. Dür +2
We propose the use of quantum optical systems to perform universal simulation of quantum dynamics. Two specific implementations that require present technology are put forward for…
On the continuity of asymptotic measures of entanglement
G. Vidal
We show that, in any open set of distillable states, all asymptotic entanglement measures are continuous as a function of (a single copy of) , even though they quantify t…
On the structure of a reversible entanglement generating set for three--partite states
A. Acin, G. Vidal, J. I. Cirac
We show that Einstein--Podolsky--Rosen--Bohm (EPR) and Greenberger--Horne--Zeilinger--Mermin (GHZ) states can not generate, through local manipulation and in the asymptotic limit,…
Time-optimal Hamiltonian simulation and gate synthesis using homogeneous local unitaries
Ll. Masanes, G. Vidal, J. I. Latorre
Motivated by experimental limitations commonly met in the design of solid state quantum computers, we study the problems of non-local Hamiltonian simulation and non-local gate synt…
