Synchronized photons, molecular light? How might this be used?

This might solve the diffusion problem for deep space issues. I see this problem

lets say the work pairing two electrons is X relative to creating two close by but not molecular photons, then my thinking is then for creating 3 or a trimer, it would be X^3/2. Two combine 4 would be X², and so on, so that by the time one had a decamer, the difficulty would outweigh any poosible gain. OTOH, this maybe away of bunching 3 photos and lowering the quantum effects of uncertainty. But in space it may only half the diffusion, so if it takes twice the effort to make the light molecule, it would not be worth it.
