Row over newspaper’s cartel plea
Mexican officials denounce a newspaper editorial which called for truce with drug cartels in Ciudad Juarez, the northern city racked by violence.
Downward spiral  Is Mexico becoming like 1980s drugs-wracked Colombia?

AFGHANISTAN: Another election, another cycle of fraud and violence?
A year after the fraud-marred presidential polls, Afghans go to the polls Sept. 18 in the country’s second parliamentary elections since 2001. But will these elections see a repeat of problems that plagued last year’s vote?
   
 

 

 

 
                  Physics:
  Microwave Manipulation
Jelena Stajic Optical lattices populated by neutral atoms are a good candidate for storing quantum information. Normally, internal degrees of freedom such as the hyperfine state are used to create the basic information unit, the qubit. However, atoms also possess motional degrees of freedom; for example, the confinement of atoms in the lattice wells creates quantized vibrational states. These motional degrees of freedom are usually controlled by introducing time-dependent lattice potentials. Now, Förster et al. use microwave fields to effect transitions between vibrational levels of opposite hyperfine states of Cs atoms. Atoms in the two hyperfine states are loaded into two lattices spatially offset from each other. This arrangement enables transitions between different vibrational states, but the probability depends on the overlap of the (offset) wave functions. If the lattice is deep, transitions only happen between neighboring, slightly offset wells; if it is shallow, the offset can be increased and the atom becomes delocalized. Effective initialization into the lowest vibrational state is achieved, and Rabi oscillations between arbitrary vibrational states are demonstrated. This approach may lead to full control of quantum transport, likely a necessity for processing quantum information in this system.
