Quantum Fractional Revival on Graphs

2018 · arXiv (Cornell University)

Fractional revival is a quantum transport phenomenon important for entanglement generation in spin networks. This takes place whenever a continuous-time quantum walk maps the characteristic vector of a vertex to a superposition of the characteristic …

The average search probabilities of discrete-time quantum walks

2021 · arXiv (Cornell University)

We study the average probability that a discrete-time quantum walk finds a marked vertex on a graph. We first show that, for a regular graph, the spectrum of the transition matrix is determined by the …
