Framework for discrete-time quantum walks and a symmetric walk on a binary tree
discrete-time quantum walks symmetric walk Framework Quantum Physics
2011/10/9
Abstract: We formulate a framework for discrete-time quantum walks, motivated by classical random walks with memory. We present a specific representation of the classical walk with memory 2 on which t...
Adiabatic Theorem for Discrete Time Evolution

2011/10/8
Abstract: A proof of the adiabatic theorem for quantum systems whose time evolution proceeds along discrete time, e.g., quantum maps and quantum circuits, is shown.
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...
We consider crossovers with respect to the weak convergence theorems from a discrete-time quan-
tum walk (DTQW). We show that a continuous-time quantum walk (CTQW) and discrete- and
continuous-time ...
Limit Theorems for the Discrete-Time Quantum Walk on a Graph with Joined Half Lines
Theorems Discrete-Time Quantum Walk Graph Half Lines
2010/10/18
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...
Discrete Time and Finite State Reflected Backward Stochastic Difference Equations
BSDE DF-RBSDE Comparison Theorem g-martingale mul-tiple prior martingale Knightian uncertainty
2010/4/27
In this paper, we firstly establish the discrete time and finite state reflected backward stochastic difference equations(DF-RBSDEs for short); then we explore the corresponding basic properties and t...
We show that certain types of quantum walks can be modeled as waves that propagate in a medium with phase and group velocities that are explicitly calculable. Since the group and phase velocities indi...
