Entanglement of qutrits
Alexander A. Klyachko, Barış Öztop, A.S. Shumovsky · Laser Physics · 2007
For two types of qutrits specified by the dynamical symmetry SU(3) and SU(2), we consider the difference in entanglement caused by the lack of quantum observables in the latter case. In particular, we show that the SU(2) qutrits can have specific separable entanglement caused by quantum correlations of intrinsic degrees of freedom in a single party without interparty correlations.
