Pretty Good State Transfer and Minimal Polynomials
Christopher M. van Bommel
We examine conditions for a pair of strongly cospectral vertices to have pretty good quantum state transfer in terms of minimal polynomials, and provide cases where pretty good sta…

Pretty Good State Transfer of Multiple Qubit States on Paths
Christopher M. van Bommel
We discuss pretty good state transfer of multiple qubit states and provide a model for considering state transfer of arbitrary states on unmodulated XX-type spin chains. We then pr…

Improving the query complexity of quantum spatial search in two dimensions
Abhijith J., Apoorva Patel
The question of whether quantum spatial search in two dimensions can be made optimal has long been an open problem. We report progress towards its resolution by showing that the or…
