From what I understand they don't really have easy access. Higher TL worlds might potentially find them, and being a high TL world immediatly reverse engineer the principals behind a conveyor, or at least the physical components to build one. From there they learn the principals, and finally build one of the conveyors that can jump quantums on its own. And remember they are a higher TL so anything infinity can build the high TL world can at least copy.

Also IIRC essentially all science in homeline has become parachronics or reverse engineering stolen tech. So yes, yes infinity does use tech to speed its progress.

I suppose the better question is why would a group like the Cabal use lower TL gear since they are probably unworried about someone reverse engineering there psionics. (Actually what TL gear does the Cabal normally use?)
