    • There are an infinite number of such bases, so there is substantial flexibility in choosing tomographic input and measurement settings. We encode qubits in polarization, with |H> = |0> and √|V> = |1>. Then √2|D(A)> = |H> + (-)|V> and √2|L(R)> = |H> + (-)i|V>. Our QPT input states |Control Target> are taken from {HH, VH, DV, LH, LV, VV, HV, HA, HL, LL, LA, DA, DR, VA, VL, DH} and measurements |CT> from {HH, HV, VH, VV, HD, HL, VL, VD, DD, RL, RD, DR, DV, RV, DH, RH}
