Pretty good quantum state transfer via transcendental edge weights
Addison Ballif, Mark Kempton, James B. Larsen +3
We prove that if we take a rooted product of a circulant graph with universal perfect state transfer with a path of fixed length whose end edge is weighted with a transcendental nu…

Controlling quantum state transfer in rooted products
Addison Ballif, Christino Tamon, Gabriel Tucker
Godsil and McKay (1978) showed that the rooted product is a powerful tool for constructing non-isomorphic cospectral pairs of graphs. Despite lacking a convenient tensor product st…
