Extrema of discrete Wigner functions and applications
Andrea Casaccino, Ernesto F. Galvao, Simone Severini
We study the class of discrete Wigner functions proposed by Gibbons et al. [Phys. Rev. A 70, 062101 (2004)] to describe quantum states using a discrete phase-space based on finite…

An application of the Deutsch-Josza algorithm to formal languages and the word problem in groups
Michael Batty, Andrea Casaccino, Andrew J. Duncan +2
We adapt the Deutsch-Josza algorithm to the context of formal language theory. Specifically, we use the algorithm to distinguish between trivial and nontrivial words in groups give…
