Diagonal unitary and orthogonal symmetries in quantum theory II: Evolution operators
Satvik Singh, Ion Nechita
We study bipartite unitary operators which stay invariant under the local actions of diagonal unitary and orthogonal groups. We investigate structural properties of these operators…
Entanglement criteria for the bosonic and fermionic induced ensembles
Stephane Dartois, Ion Nechita, Adrian Tanasa
We introduce the bosonic and fermionic ensembles of density matrices and study their entanglement. In the fermionic case, we show that random bipartite fermionic density matrices h…
A geometrical description of the universal asymmetric quantum cloning region
Ion Nechita, Clément Pellegrini, Denis Rochette
We consider the problem of determining the achievable region of parameters for universal asymmetric quantum cloning. Measuring the cloning performance with the figure of…
Maximal violation of steering inequalities and the matrix cube
Andreas Bluhm, Ion Nechita
In this work, we characterize the amount of steerability present in quantum theory by connecting the maximal violation of a steering inequality to an inclusion problem of free spec…
Generating series and matrix models for meandric systems with one shallow side
Motohisa Fukuda, Ion Nechita
In this article, we investigate meandric systems having one shallow side: the arch configuration on that side has depth at most two. This class of meandric systems was introduced a…
