Matrix product states represent ground states faithfully
F. Verstraete, J. I. Cirac
We quantify how well matrix product states approximate exact ground states of 1-D quantum spin systems as a function of the number of spins and the entropy of blocks of spins. We a…
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…
Experimental demonstration of quantum memory for light
Brian Julsgaard, Jacob Sherson, J. Ignacio Cirac +2
The information carrier of today's communications, a weak pulse of light, is an intrinsically quantum object. As a consequence, complete information about the pulse cannot, even in…
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…
