GroupFunctions.jl: computing individual entries of the irreducible representations of the unitary group U(d)
David Amaro-Alcalá, Konrad SzymaÅski
GroupFunctions.jl is a Julia library for computing individual matrix elements of irreducible representations of U(d). These matrix elements, called group functions, can be evaluate…

Useful entanglement can be extracted from noisy graph states
Konrad SzymaÅski, Lina Vandré, Otfried Gühne
Cluster states and graph states in general offer a useful model of the stabilizer formalism and a path toward the development of measurement-based quantum computation. Their defini…
