based on searching for a vertex in a graph with multiple marked vertices, with Ambainis's …

Staggered quantum walks on graphs

R Portugal - Physical Review A, 2016 - APS
The staggered quantum-walk model makes it possible to establish an unprecedented
connection between discrete-time quantum walks and graph theory. We call attention to the …

Perfect state transfer by means of discrete-time quantum walk search algorithms on highly symmetric graphs

M Štefaňák, S Skoupý - Physical Review A, 2016 - APS
Perfect state transfer between two marked vertices of a graph by means of a discrete-time
quantum walk is analyzed. We consider the quantum walk search algorithm with two marked …

Partition-based discrete-time quantum walks

N Konno, R Portugal, I Sato, E Segawa - Quantum Information Processing, 2018 - Springer
We introduce a family of discrete-time quantum walks, called two-partition model, based on
two equivalence-class partitions of the computational basis, which establish the notion of …

Szegedy's quantum walk with queries

RAM Santos - Quantum Information Processing, 2016 - Springer
When searching for a marked vertex in a graph, Szegedy's usual search operator is defined
by using the transition probability matrix of the random walk with absorbing barriers at the …

Equivalence of Szegedy's and coined quantum walks

TG Wong - Quantum Information Processing, 2017 - Springer
Szegedy's quantum walk is a quantization of a classical random walk or Markov chain,
where the walk occurs on the edges of the bipartite double cover of the original graph. To …
