Hypergraph states in Grover's quantum search algorithm
Matteo A. C. Rossi, Dagmar Bruß, Chiara Macchiavello · Physica Scripta · 2014
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.
