Quantum Search with a Generalized Laplacian
Jonas Duda, Molly E. McLaughlin, Thomas G. Wong
A single excitation in a quantum spin network described by the Heisenberg model can effect a variety of continuous-time quantum walks on unweighted graphs, including those governed…

Quantum Search with the Signless Laplacian
Molly E. McLaughlin, Thomas G. Wong
Continuous-time quantum walks are typically effected by either the discrete Laplacian or the adjacency matrix. In this paper, we explore a third option: the signless Laplacian, whi…
