By Kate McAlpine FAST quantum computers made of atoms trapped by beams of light could be a step closer, thanks to the first images of the individual atoms in such a grid. Quantum computers get their speed from the fact that their components can occupy a range of states rather than just two as in a binary computer. Special algorithms can exploit these quantum states to solve problems that would defeat a conventional computer. One candidate for such a computer is a so-called optical lattice, in which ultracold atoms are coaxed by strategically placed laser beams into a grid arrangement,
