Spatial search for a general multi-vertex state on graph by continuous-time quantum walks
Xi Li, Hanwu Chen, Yue Ruan +3
In this work, we consider the spatial search for a general marked state on graphs by continuous time quantum walks. As a simplest case, we compute the amplitude expression of the s…

The optimal search on graph by continuous-time quantum walks
Xi Li, Hanwu Chen, Yue Ruan +3
Chakraborty and Leonardo have shown that a spatial search by quantum walk is optimal for almost all graphs. However, we observed that on some graphs, certain states cannot be searc…
