Quantum walk represents one of the most promising resources for the simulation of physical quantum systems [1], and has also emerged as an alternative to the standard circuit model for quantum computi...
Limit distribution with a combination of density functions for a 2-state quantum walk

We consider 2-state time-inhomogeneous quantum walks defined by two matrices on the line. For the time-homogeneous walks determined by a unitary matrix, the limit distribution is expressed by a simple...

We study the single particle dynamics of a mobile non-Abelian anyon hopping around many pinned anyons on a surface. The dynamics is modelled by a discrete time quantum walk and the spatial degree of f...

Physicists in Austria have demonstrated a "quantum walk" in detail for the first time, using trapped ions. Such experiments could allow us to better understand the transition between the quantum and c...

The evolution operator of a discrete-time quantum walk involves a conditional shift in position space which entangles the coin and position degrees of freedom of the walker. After several steps, the c...

Let p_j^(n) be the probability that a Hadamard quantum walk, started at site j on the integer lattice {0,...,n}, is absorbed at 0. We give an explicit formula for p_j^(n). Our formula proves a conject...

Quantum walks can be used either as tools for quantum algorithm development or as entanglement generators, potentially useful to test quantum hardware. We present a novel algorithm based on a discrete...

We give the first example of faster transport with a quantum walk on an inherently directed graph, on the directed line with a variable number of self-loops at each vertex. These self-loops can be tho...
