Engineering the success of quantum walk search using weighted graphs

2016 · Physical Review A

Continuous-time quantum walks are natural tools for spatial search, where one searches for a marked vertex in a graph. Sometimes the structure of the graph causes the walker to get trapped, such that the probability …

Isolated Vertices in Continuous-Time Quantum Walks on Dynamic Graphs

2019 · arXiv (Cornell University)

It was recently shown that continuous-time quantum walks on dynamic graphs, i.e., sequences of static graphs whose edges change at specific times, can implement a universal set of quantum gates. This result treated all isolated …
