Single-spin addressing in an atomic Mott insulator
With the help of a laser beam, individual atoms in the lattice of light could be adressed.

With the addressing scheme arbitrary patterns of atoms in the lattice can be prepared. The atomic patterns each consist of 10 - 30 single atoms that are kept in an artificial crystal of light.
