Spatial search using the discrete time quantum walk
Spatial search discrete time quantum walk
2010/11/8
We study the quantum walk search algorithm of Shenvi, Kempe and Whaley [PRA 67 052307 (2003)] on data structures of one to two spatial dimensions, on which the algorithm is thought to be less efficie...
Limit Theorems for the Discrete-Time Quantum Walk on a Graph with Joined Half Lines
Theorems Discrete-Time Quantum Walk Graph Half Lines

We consider a discrete-time quantum walk Wt, at time t on a graph with joined half lines J, which is composed of half lines with the same origin. Our analysis is based on a reduction of the walk o...
