    • One-dimensional lazy quantum walks and occupancy rate 

      Li, Dan; Gettrick, Michael Mc; Zhang, Wei-Wei; Zhang, Ke-Jia (IOP Publishing, 2015-04-30)
      In this paper, we discuss the properties of lazy quantum walks. Our analysis shows that the lazy quantum walks have O(t(n)) order of the n-th moment of the corresponding probability distribution, which is the same as that ...

    • Quantum walks on two kinds of two-dimensional models 

      Li, Dan; Mc Gettrick, Michael; Zhang, Wei-Wei; Zhang, Ke-Jia (Springer Nature, 2015-01-21)
      In this paper, we numerically study quantum walks on two kinds of two-dimensional graphs: cylindrical strip and Mobius strip. The two kinds of graphs are typical two-dimensional topological graph. We study the crossing ...
