No, you are dead BEFORE you are alive which isn't any more of a paradox than being alive before you were alive. In 1000 AD there isn't a dead me and a live me at the same time (ala Schrodinger). From that prespective, it's no different than me being alive now and dead in the future. To the universe, there is no difference particle-wise between a living or dead creature. As one famous time traveler stated, "Life is just the Univierse's way of keeping meat fresh."

The live/dead situation you describe isn't the same as Schrodinger's Cat. In this case, both the live and dead me would exist and could be observed by the same observer at the same time. There would be no collapse of the waveform to a single state.

FYI, I have a master's in quantum physics.

In reality, the paradox occured when the time travel took place. By traveling backwards in time you've essentially created matter and energy out of nothing. The amount of matter/energy in the universe is constant. The particles that eventually became you already existed back in 1000 AD. They can't exist there in two places at the same time. To the universe, it'd look like new matter suddenly popped into existence. The Universe HATES that when it happens.

Of course, this could be circumvented if you were recreated out of atoms present in the past, but that could be very messy if things went wrong.
