Pretty good state transfer among large sets of vertices
Ada Chan, Peter Sin
In a continuous-time quantum walk on a network of qubits, pretty good state transfer is the phenomenon of state transfer between two vertices with fidelity arbitrarily close to 1.…
State Transfer in Complex Quantum Walks
Antonio Acuaviva, Ada Chan, Summer Eldridge +5
Given a graph with Hermitian adjacency matrix , perfect state transfer occurs from vertex to vertex if the -entry of the unitary matrix has unit magn…
Quantum isomorphism of graphs from association schemes
Ada Chan, William J. Martin
We show that any two Hadamard graphs on the same number of vertices are quantum isomorphic. This follows from a more general recipe for showing quantum isomorphism of graphs arisin…
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…
Pretty good state transfer in discrete-time quantum walks
Ada Chan, Hanmeng Zhan
We establish the theory for pretty good state transfer in discrete-time quantum walks. For a class of walks, we show that pretty good state transfer is characterized by the spectru…
Laplacian Fractional Revival on Graphs
Ada Chan, Bobae Johnson, Mengzhen Liu +3
We develop the theory of fractional revival in the quantum walk on a graph using its Laplacian matrix as the Hamiltonian. We first give a spectral characterization of Laplacian fra…
