SUMMARY
The authors call these functionals "qubit functionals" (because they are functionals on the qubit values) and focus on their roles in how the entries of the quantum state vectors are modified collectively by quantum gates. The authors see that U1 pairs a0 with a4, a 1 with a0 u1 a0 + u2 a4=pair e_g a0 and a4, the effect of U1 is equivalent to U, thus the authors can say a0 plays the role a4 u2 a0 - u1 a4 of "0" in this 2-dimensional subspace while a4 plays the role of "1".
