Performance of quantum phase gates with cold trapped atoms
A. Negretti, T. Calarco, M. A. Cirone +1
We examine the performance of a quantum phase gate implemented with cold neutral atoms in microtraps, when anharmonic traps are employed and the effects of finite temperature are a…
Correlated motion of two atoms trapped in a single mode cavity field
J. K. Asbóth, P. Domokos, H. Ritsch
We study the motion of two atoms trapped at distant positions in the field of a driven standing wave high-Q optical resonator. Even without any direct atom-atom interaction the ato…
Multi-party entanglement in graph states
M. Hein, J. Eisert, H. J. Briegel
Graph states are multi-particle entangled states that correspond to mathematical graphs, where the vertices of the graph take the role of quantum spin systems and edges represent I…
Local invariants for multi-partite entangled states allowing for a simple entanglement criterion
Hans Aschauer, John Calsamiglia, Marc Hein +1
We present local invariants of multi-partite pure or mixed states, which can be easily calculated and have a straight-forward physical meaning. As an application, we derive a new e…
Fast and robust two-qubit gates for scalable ion trap quantum computing
J. J. Garcia-Ripoll, P. Zoller, J. I. Cirac
We propose a new concept for a two-qubit gate operating on a pair of trapped ions based on laser coherent control techniques. The gate is insensitive to the temperature of the ions…
