Pretty good plus state transfer in cycles
Sarojini Mohapatra, Hiranmoy Pal
We investigate fractional revival in graphs with respect to the adjacency, Laplacian, and signless Laplacian matrices. We observe that, under certain conditions, fractional revival…

Quantum walks on finite and bounded infinite graphs
Chris Godsil, Steve Kirkland, Sarojini Mohapatra +2
A weighted graph with countable vertex set is bounded if there is an upper bound on the maximum of the sum of absolute values of all edge weights incident to a vertex in . I…

Quantum Pair State Transfer on Isomorphic Branches
Hiranmoy Pal, Sarojini Mohapatra
The evolution of certain pair state in a quantum network with isomorphic branches, governed by the Heisenberg Hamiltonian, depends solely on the local structure, and it remain…
