The Physical Implementation of Quantum Computation David P. DiVincenzo
... A qubit being “well characterized” means several different things. Its physical parameters should be accurately known, including the internal Hamiltonian of the qubit (which determines the energy eigenstates of the qubit, which are often, although not always, taken as the |0i and |1i states), the pr ...

... In this way the lower bound will appear as a simple function of the area spanned by the commutators i[A, ρ], i[B, ρ] in the tangent space to the state ρ, provided the state space is equipped with a suitable monotone metric (see Theorem 6.1).
