Non-linear Quantum Walks

Quantum Walks (QWs) are devised as an important ingredient of quantum computation. Several physical systems have been proposed to implement them. I will discuss a non-linear QW which gives rise to interesting phenomena, including the formation of soliton structures. Depending on the strength of the non-linearity, one finds different regimes for the behavior of the solitons. The region with large values of the strength parameter shows a chaotic dependence.
