Of Shadows and Gaps in Spatial Search
Ada Chan, Chris Godsil, Christino Tamon +1
Spatial search occurs in a connected graph if a continuous-time quantum walk on the adjacency matrix of the graph, suitably scaled, plus a rank-one perturbation induced by any vert…
Quantum Fractional Revival on Graphs
Ada Chan, Gabriel Coutinho, Christino Tamon +2
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 chara…
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…
