The curious thing about entanglement is that this shared existence continues even when the photons are separated by vast distances. So a measurement on one immediately influences the state of the other, regardless of the distance between them."
Information is everything. If information can be instantly transferred from one place to another... to heck with space travel. Just beam yourself to Alpha Centauri and skip all the annoying travel time and discomfort.
And when you get there? You haven't aged. Because your body has been frozen in an information-only state during the transportation, there is no degradation.
Weirdness... and now I want to go write some sci-fi...
It would require a perfect measurement of your state (this means all of your constituent particles) on Earth. Around 10^29 baryons + about the same order of magnitude of electrons that you need to 'encode' is a pretty large amount of things you can get wrong before getting to the 'information-only' state. Then you need to build it back.
