The geometry of bipartite qutrits including bound entanglement
B. Baumgartner, B. C. Hiesmayr, H. Narnhofer
We investigate the state space of bipartite qutrits. We construct an analog to the "magic" tetrahedron for bipartite qubits--a magic simplex W. It is formed by all convex combinati…
A special simplex in the state space for entangled qudits
Bernhard Baumgartner, Beatrix Hiesmayr, Heide Narnhofer
Focus is on two parties with Hilbert spaces of dimension d, i.e. "qudits". In the state space of these two possibly entangled qudits an analogue to the well known tetrahedron with…
The state space for two qutrits has a phase space structure in its core
Bernhard Baumgartner, Beatrix C. Hiesmayr, Heide Narnhofer
We investigate the state space of bipartite qutrits. For states which are locally maximally mixed we obtain an analog of the ``magic'' tetrahedron for bipartite qubits--a magic sim…
