%0 Journal Article %T Ito's formula for the discrete-time quantum walk in two dimensions %A Clement Ampadu %J Physics %D 2012 %I arXiv %X Following [Konno, arXiv:1112.4335], it is natural to ask: What is the Ito's formula for the discrete time quantum walk on a graph different than Z, the set of integers? In this paper we answer the question for the discrete time quantum walk on Z^2, the square lattice. %U http://arxiv.org/abs/1203.0935v1
