Localizable Entanglement
M. Popp, F. Verstraete, M. A. Martin-Delgado +1
We consider systems of interacting spins and study the entanglement that can be localized, on average, between two separated spins by performing local measurements on the remaining…
Coherent control of trapped ions using off-resonant lasers
J. J. Garcia-Ripoll, P. Zoller, J. I. Cirac
In this paper we develop a unified framework to study the coherent control of trapped ions subject to state-dependent forces. Taking different limits in our theory, we can reproduc…
Quantum information processing using localized ensembles of nuclear spins
J. M. Taylor, G. Giedke, H. Christ +5
We describe a technique for quantum information processing based on localized en sembles of nuclear spins. A qubit is identified as the presence or absence of a collective excitati…
Renormalization algorithms for Quantum-Many Body Systems in two and higher dimensions
F. Verstraete, J. I. Cirac
We describe quantum many--body systems in terms of projected entangled--pair states, which naturally extend matrix product states to two and more dimensions. We present an algorith…
Spin dynamics for bosons in an optical lattice
J. J. Garcia-Ripoll, J. I. Cirac
We study the internal dynamics of bosonic atoms in an optical lattice. Within the regime in which the atomic crystal is a Mott insulator with one atom per well, the atoms behave as…
Matrix Product Density Operators: Simulation of finite-T and dissipative systems
F. Verstraete, J. J. Garcia-Ripoll, J. I. Cirac
We show how to simulate numerically both the evolution of 1D quantum systems under dissipation as well as in thermal equilibrium. The method applies to both finite and inhomogeneou…
