Isn't this just the usual quantum tunneling? Since particle positions
are not exact on sufficient small scales, the electrons can jump across
insulating voids where it classically would have been forbidden. It is a
well understood effect and not particularly spooky compared to much
other quantum stuff (the Aharonov-Bohm effect - *that's* spooky!).
The effect doesn't involve jumping across universes even in the many 
worlds interpretations; there the electron simply does travel another 
way in different universes and sometimes we find ourselves in the 
slighly unlikely but still possible universe where it tunneled. 
The problem with using "nearby" universes where the other invisible 
universe contains useful stuff like superconductors or superfast 
transistors is that in reality such possible universes are extremely 
remote compared to the myriad of universes where you have a copy of your 
device with a slighly different thermal noise. So even if particles did 
jump across universes (which they don't in the MWI, at least not unless 
you have some kind of meta-superspace model) they would interact with 
other processors similarly lacking parts.
