The state-dependent (quantum) transport [1] of neutral atoms stored in a one dimensional optical lattice is a promising technique to implement controlled interactions between them using coherent cold collisions [2]. This is required in several schemes of quantum information processing. Here, we focus on the technical implementation of the quantum transport for single Caesium atoms, as well as the manipulation and detection of their internal states.
Multiple quantum transport steps in combination with microwave-operations on the internal state of an atom promise to implement various one dimensional quantum walks [3]. Using the quantum transport with two or more atoms we plan to investigate atom-atom interactions by overlapping their wave-functions within a predetermined lattice site.
