Quantum Computing with Trapped Particles in Microscopic Potentials
Tommaso Calarco, D. Jaksch, J. I. Cirac, P. Zoller, Hans J. Briegel · 2000
We review recent proposals for performing entanglement manipulation via controlled interactions between trapped atoms. State-dependent, time-varying microscopic potentials allow one to obtain with high fidelity a conditional phase shift realizing a universal quantum gate. We discuss possible physical implementations with existing experimental techniques, for example optical lattices and magnetic micro-traps.
