Ito’s Formula for the Discrete-Time Quantum Walk in Two Dimensions
Clement Boateng Ampadu · Journal of Quantum Information Science · 2012
Following Konno [1], 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 Z2, the square lattice.
