Hypergraph states in Grover's quantum search algorithm
arXiv:1404.1285 · doi:10.1088/0031-8949/2014/T160/014036
Abstract
We study the entanglement content of the states employed in the Grover algorithm after the first oracle call when a few searched items are concerned. We then construct a link between these initial states and hypergraphs, which provides an illustration of their entanglement properties.
