The researchers focused the smaller laser beams through the cloud of ultracold atoms and found that each beam's focus — the point at which the beam's intensity was highest — attracted a single atom, essentially picking it out from the cloud and holding it in place.
Another far more arduous and painstaking technique involves dragging and placing atoms one by one using an atomic force microscope or a scanning tunnelling microscope (STM), both of which are sensitive enough to move single atoms around on a surface with a fine tip.
Instead of trying to measure the mass directly, the researchers bound a single electron to a bare carbon nucleus and placed the resulting atom in a uniform electromagnetic field called a Penning trap (created in an apparatus similar to the one pictured above).
«Our decade - long research program had already established the most long - lived quantum bit in the solid state, by encoding quantum information in the spin of a single phosphorus atom inside a silicon chip, placed in a static magnetic field.»
«The surface of a metal has one energy potential — it is uniform,» explains co-author Klaus Attenkofer, «whereas on a single atom, every place on the surface has a different kind of energy.»
