quantum telephone

The future of telecommunications may hinge on a clever new version of a device from its past, physicists claim. What the Bell telephone is to communication across town or overseas, the Bell telegraph -- named for British physicist J.S. Bell -- may become to communication across the solar system or even the Milky Way.
1) The particles must be entangled a priori to be usable. You can't just plug your quantum telephone into the network and start yapping.
2) The entanglement process always involves a collision. The two entangled particles are then moving at high velocities away from each other. The act of slowing them down (so they can be stored in your quantum phone) must involve another collision, and the entanglement will be lost.
3) You can't ever know when someone is sending you a message on your quantum phone, because you can't look at the state of your entangled particles without disturbing them, and that disturbance will ruin the entanglement.
There are others, give me a moment to get my head straight.

ummm that's what engineering does...solve physical challenges...unless your on nickelodeon and watching double dare then it's just a bunch of punk ass kids jumping into vats of slime.
