Quantum State Transfer on Coronas
Ethan Ackelsberg, Zachary Brehm, Ada Chan +2
We study state transfer in quantum walk on graphs relative to the adjacency matrix. Our motivation is to understand how the addition of pendant subgraphs affect state transfer. For…

Laplacian State Transfer in Coronas
Ethan Ackelsberg, Zachary Brehm, Ada Chan +2
We prove that the corona product of two graphs has no Laplacian perfect state transfer whenever the first graph has at least two vertices. This complements a result of Coutinho and…
