I'm not sure what device you are refering to (I'm not that much of a
quantum person), but there are several mindboggling ways to handle quantum
information that might appear like this (quantum teleportation, for
example). But I seriously doubt it would remove the Uncertainty Principle,
since that Principle is fundamental to QM and we would get some very nasty
paradoxes without it.
