Laser-trapped atoms in strings can be deftly rearranged and the spacing between them precisely adjusted.

Laser cooling and trapping techniques allow us to control and manipulate neutral atoms1. Here we rearrange, with submicrometre precision, the positions and ordering of laser-trapped atoms within strings by manipulating individual atoms with optical tweezers2. Strings of equidistant atoms created in this way could serve as a scalable memory for quantum information3.
