the spin of a particle or the polarization of a photon, is transferred from one place to another, without traveling through any physical medium.

If true teleportation of people ever becomes possible it would lead to some interesting moral questions. Since no matter is actually being transferred, you would end up with a copy in a sense. The star trek transporters we think of would basically have to vaporize the original.

At least that's my take on it. More interestin stuff fer ponderin.

What the big goal here is not just secure communications, but doing so over increasing distances.

For instance, at the speed of light, just communicating with someone on Mars would be delayed anywhere from 3 to 22 minutes, unless a quantum communications device was used.

But this raises a question: can such communications defeat causality? So far, the answer seems to be “no”.

Without going into a lot of detail:

The article seems to discuss this in terms of information transfer. Seems like part of the information transferred would be the kinetic energy level of the original ion.

If the transfer occurs over any substantial distance north and south, seems like the kinetic energy level will be out of sync with the location transferred to unless the information is altered to allow for that. If they can alter the information transferred, that makes for interesting possibilities.

Probably.
