New, Better Way to Build Circuits for World's First Useful Quantum Computers (IMAGE)
Caption
The research team led by David Weiss at Penn State University performed a specific single quantum operation on individual atoms in a P-S-U pattern on three separate planes stacked within a cube-shaped arrangement. The team then used light beams to selectively sweep away all the atoms that were not targeted for that operation. The scientists then made pictures of the results by successively focusing on each of the planes in the cube. The photos, which are the sum of 20 implementations of this process, show bright spots where the atoms are in focus, and fuzzy spots if they are out of focus in an adjacent plane -- as is the case for all the light in the two empty planes. The photos also show both the success of the technique and the comparatively small number of targeting errors.
