It demonstrates experimental appli-cations of this transport, including a single atom interferometer, a quantum walkand controlled two-atom collisions. The atoms are stored one by one in an opticallattice formed by a standing wavedipole trap. Their positions are determined withsub-micrometer precision, while atom pair separations are reliably inferred downto neighboring lattice sites using real-time numerical processing. Using microwavepulsesinthepresenceofamagneticfieldgradient,theinternalqubitstates,encodedin the hyperfinelevels of the atoms, can be separately initialized and manipulated.
