Designing spin-1 lattice models using polar molecules
Gavin K. Brennen, Andrea Micheli, Peter Zoller
We describe how to design a large class of always on spin-1 interactions between polar molecules trapped in an optical lattice. The spin degrees of freedom correspond to the hyperf…
Nonlinear entanglement witnesses, covariance matrices and the geometry of separable states
Otfried Gühne, Norbert Lütkenhaus
Entanglement witnesses provide a standard tool for the analysis of entanglement in experiments. We investigate possible nonlinear entanglement witnesses from several perspectives.…
High fidelity transfer of an arbitrary quantum state between harmonic oscillators
K. Jahne, B. Yurke, U. Gavish
It is shown that by switching a specific time-dependent interaction between a harmonic oscillator and a transmission line (a waveguide, an optical fiber, etc.) the quantum state of…
Covariance matrices and the separability problem
O. Gühne, P. Hyllus, O. Gittsovich +1
We propose a unifying approach to the separability problem using covariance matrices of locally measurable observables. From a practical point of view, our approach leads to strong…
Experimental Realization of Deutsch's Algorithm in a One-way Quantum Computer
M. S. Tame, R. Prevedel, M. Paternostro +3
We report the first experimental demonstration of an all-optical one-way implementation of Deutsch's quantum algorithm on a four-qubit cluster state. All the possible configuration…
Classical spin models and the quantum stabilizer formalism
M. Van den Nest, W. Dür, H. J. Briegel
We relate a large class of classical spin models, including the inhomogeneous Ising, Potts, and clock models of q-state spins on arbitrary graphs, to problems in quantum physics. M…
