Unital Positive Maps and Quantum States
M. Asorey, A. Kossakowski, G. Marmo +1
We analyze the structure of the subset of states generated by unital completely positive quantum maps, A witness that certifies that a state does not belong to the subset generated…

Semigroup of positive maps for qudit states and entanglement in tomographic probability representation
V. I. Man'ko, G. Marmo, A. Simoni +1
Stochastic and bistochastic matrices providing positive maps for spin states (for qudits) are shown to form semigroups with dense intersection with the Lie groups $IGL(n, \mathbb{R…

Frame transforms, star products and quantum mechanics on phase space
P. Aniello, V. I. Man'ko, G. Marmo
Using the notions of frame transform and of square integrable projective representation of a locally compact group , we introduce a class of isometries (tight frame transforms)…
