Manifolds of interconvertible pure states
Magdalena M. Sinolecka, Karol Zyczkowski, Marek Kus
Local orbits of a pure state of an N x N bi-partite quantum system are analyzed. We compute their dimensions which depends on the degeneracy of the vector of coefficients arising b…

Separable approximation for mixed states of composite quantum systems
Thomas Wellens, Marek Kus
We describe a purely algebraic method for finding the best separable approximation to a mixed state of a composite 2x2 quantum system, consisting of a decomposition of the state in…
