An international team has identified a new hybrid atom that could be used to develop quantum computers. This data visualisation shows an electron density map of the material. The funnel- or vortex-shaped figure in the lower left is an arsenic atom, and the saucer-shaped image in the centre is a map of an electron binding to various atoms (each dot represents one location). The yellow dots in the upper left-centre are the electron in the quantum state. (Purdue University image/David Ebert)
