Recently, Ars Technica ran a monumental article on beaming in Star Trek and its implications, and more importantly, whether it's plausible to beam consciousness without killing us in the process.
It seems possible in the Star Trek universe. However, currently physicists find the idea absurd and unreal because there's no way you can transport matter and its quantum state without first destroying it and then recreating it perfectly, due to Heisenberg’s Uncertainty Principle. The biggest conundrum of all is the fact that pretty much everyone understands that conciousness is a physical state of the brain, which features continuity as its primary principle; yet it surely seems like copying the said state produces a new person altogether, which brings up the problem of conciousness becoming local to one's skull and inseparable from gray matter; this idea sounds a bit unscientific because it introduces the notion that there's something about our brain which cannot be described in terms of physics, almost like soul.
This also brings another very difficult question: how do we know if we are the same person when we wake up in the morning or after we were put under during general anaesthesia?
