30. This assumption is not restrictive, since we can always prepare the total system in this class of states by performing a measurement on X to confirm it in the state | X.
31. The condition Ω=ω is readily and naturally follows, if, for instance, the two qubits are realized by two spins with the same magnetic moment. Another example would be given by two identical atoms in a linear trap.
