Atoms in optical lattices

POSITION AND MOMENTUM ENTANGLEMENT OF DIPOLE-DIPOLE INTERACTING ATOMS IN OPTICAL LATTICES... 

Also the influence of magnetic flelds on the behaviour of trapped atoms has been studied. One example is the Meissner effect, which was first discovered for supra-conducting solids and has now been investigated for atoms in optical lattices in external magnetic fields [1205].

Many systems are being studied to manipulate quantum information. Some make use of individual atoms cold trapped ions, neutral atoms in optical lattices, atoms in crystals. Other involve particle spins or photons in cavity QED or nonlinear optical setups as well as more exotic ones where geometric combinations of elementary excitations are defined as qubits, such as in topological quantum computing [8]. However, none of these systems has yet emerged as a definitive way to build a quantum information processor. A reason for this is that there is an essential dichotomy we need... 

The maximum densities of atoms in optical lattices are typically limited to values of the order of cm , mainly because of absorption and scattering of the...
