Transporting, splitting and merging of atomic ensembles in a chip trap
P. Hommelhoff, W. Hänsel, T. Steinmetz +2
We present a toolbox for cold atom manipulation with time-dependent magnetic fields generated by an atom chip. Wire layouts, detailed experimental procedures and results are presen…
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…
Bell Inequalities for Graph States
Otfried Guehne, Geza Toth, Philipp Hyllus +1
We investigate the non-local properties of graph states. To this aim, we derive a family of Bell inequalities which require three measurement settings for each party and are maxima…
The optimal cloning of quantum coherent states is non-Gaussian
N. J. Cerf, O. Krueger, P. Navez +2
We consider the optimal cloning of quantum coherent states with single-clone and joint fidelity as figures of merit. Both optimal fidelities are attained for phase space translatio…
