Quantum walk of a trapped ion in phase space

H Schmitz, R Matjeschk, C Schneider, J Glueckert… - Physical review …, 2009 - APS
We implement the proof of principle for the quantum walk of one ion in a linear ion trap. With
a single-step fidelity exceeding 0.99, we perform three steps of an asymmetric walk on the …

Quantum walks

N Konno - Lecture notes in mathematics, 2008 - Springer
Quantum walks can be considered as a generalized version of the classical random walk.
There are two classes of quantum walks, that is, the discrete-time (or coined) and the …

[图书][B] Atom chips

J Reichel, V Vuletic - 2011 - books.google.com
This stimulating discussion of a rapidly developing field is divided into two parts. The first

Two-particle quantum walks applied to the graph isomorphism problem

JK Gamble, M Friesen, D Zhou, R Joynt… - Physical Review A …, 2010 - APS
We show that the quantum dynamics of interacting and noninteracting quantum particles are
fundamentally different in the context of solving a particular computational problem …

Optimizing the discrete time quantum walk using a SU (2) coin

CM Chandrashekar, R Srikanth, R Laflamme - Physical Review A—Atomic …, 2008 - APS
We present a generalized version of the discrete time quantum walk, using the SU (2)
operation as the quantum coin. By varying the coin parameters, the quantum walk can be …

Relationship between quantum walks and relativistic quantum mechanics

CM Chandrashekar, S Banerjee, R Srikanth - Physical Review A—Atomic …, 2010 - APS
Quantum walk models have been used as an algorithmic tool for quantum computation and
