Everything I've ever read about quantum teleportation says no [0..2]. Even if state changes are instantaneous, the transmission of information itself is still limited to the speed of light (and a ship counts as "information" in this case), and the process of quantum teleportation would require some classical communication channel to transmit state.
All that notwithstanding the amount of energy you would need to "entangle" an entire ship in the first place.
