First, the system would need to be isolated from any number of sources of interference, such as magnetic waves, light, heat, air, and sound.
The individual photons could be programmed in their configurations, whether they are polarized horizontally, vertically, or 45-degrees, to carry the values of 0, 1, or 0+1. There would be no need to carry the second 1+0 Q-bit to carry out computations, because the position of the 1 and the 0 would be ultimately the same position, so therefore the extra value could not be calculated because it is on a bit basis, not a multiple photon basis.
However, the 0+1 and 1+0 could be measured with multiple photons, in addition to other types of relationships including entanglement, when multiple photons are used to measure the computing speed.
