The mixed two-qubit system and the structure of its ring of local invariants
The local invariants of a mixed two-qubit system are discussed. These invariants are polynomials in the elements of the corresponding density matrix. They are counted by means of group-theoretic branching rules which relate this problem to one arising in spin-isospin nuclear shell models. The corres...
