From Graph States to Two-Graph States
Constanza Riera, Stephane Jacob, Matthew G. Parker
The name graph state is used to describe a certain class of pure quantum state which models a physical structure on which one can perform measurement-based quantum computing, and w…
On Pivot Orbits of Boolean Functions
Constanza Riera, Lars Eirik Danielsen, Matthew G. Parker
We derive a spectral interpretation of the pivot operation on a graph and generalise this operation to hypergraphs. We establish lower bounds on the number of flat spectra of a Boo…
Generalised Bent Criteria for Boolean Functions (II)
Constanza Riera, George Petrides, Matthew G. Parker
In the first part of this paper [16], some results on how to compute the flat spectra of Boolean constructions w.r.t. the transforms {I,H}^n, {H,N}^n and {I,H,N}^n were presented,…
Generalised Bent Criteria for Boolean Functions (I)
Constanza Riera, Matthew G. Parker
Generalisations of the bent property of a boolean function are presented, by proposing spectral analysis with respect to a well-chosen set of local unitary transforms. Quadratic bo…
