I will have to read the paper, but they are of course making assumptions that won't sit well with everyone.
First, we have no proof that the atoms exist except when measured. This solves the size issue and explains why distance does not matter for entangled items.
Second, they are working on the idea that physics here is the same in the "real world" or that there even is a real world. At the end of the day, we would be hardpressed to prove that this place only exists in a source's mind.
Last (for now), they have yet to develop quantum crystals to use in computers. This will change the way they see information.
Gosh, I have a lot of catching up to do.
