A summary of main results and concluding remarks will then be made in Section 4. We introduce basic of the discrete time quantum walks and mention the continuous time quantum walk. algorithms. @article{Piddock2019QuantumWS, title={Quantum walk search algorithms and effective resistance}, author={Stephen Piddock}, journal={arXiv: Quantum Physics}, year={2019} } Stephen Piddock Published 2019 Mathematics, Physics arXiv: Quantum Physics We consider the … We work in the framework introduced by Belovs which showed how to detect the existence of a marked vertex in $O(\sqrt{RW})$ quantum walk steps, where $R$ is the effective resistance and $W$ is the total weight of the graph. The chapter on spatial search algorithms has been rewritten to offer a more comprehensive approach and a new chapter describing the element distinctness algorithm has been added. We describe the Grover’s search algorithm and estimate its complexity. Quantum random walks on graphs have been shown to display many interesting properties, including exponentially fast hitting times when compared with their classical counterparts. PDF. will be stated as quantum analogues of classical search procedures. There is a new appendix on graph theory highlighting the importance of graph theory to quantum walks.

Quantum random walks on graphs have been shown to display many interesting properties, including exponentially fast hitting times when compared with their classical counterparts. However, it is still unclear how to use these novel properties to gain an algorithmic speedup over classical algorithms. Quantum walks are the quantum analogue of classical random walks.

Download it Quantum Walks And Search Algorithms books also available in PDF, EPUB, and Mobi Format for read it on your Kindle device, PC, phones or tablets. We consider the problem of finding a marked vertex in a graph from an arbitrary starting distribution, using a quantum walk based algorithm. Grover search and the quantum walk based search algorithms of Ambainis, Szegedy and Magniez et al. In this paper, we present a quantum search algorithm based on the quantum random-walk architecture that provides such a speedup. In this paper, we present a quantum search algorithm based on the quantum random walk architecture that provides such a speed-up. We present a rather detailed description of a somewhat simplified version of the MNRS al-gorithm. However, it is still unclear how to use these novel properties to gain an algorithmic speedup over classical algorithms.
