Neutral atoms walking in a deep optical lattice(discrete quantum walks)are exploring a large Hilbert space with spatial quantum coherence now preserved over 10 quantum sites and more in our laboratory.This situation allows to conquer new territory: with electric quantum walks momentum-space phenomena such as Bloch oscillations or Anderson like localization are realized in a single experiment.Recent extensions of our state dependent transport method allow us to perform non-invasive measurements.And with improved cooling and localization methods we are zeroing in on having controlled interactions of exactly two atoms.
