Teleportation Progress
You heard that right. And it is not tinfoil hat stuff. It is from reputable scientists. It makes intuitive sense that if superconductors can carry currents with zero resistance, then superconducting light emitting diodes might do their stuff with equally amazing efficiency.What does this have to do with teleportation? This is exciting not just because superconducting LEDs will be bright but because Cooper pairs can also produce entangled pairs of photons. That raises the prospect of intense sources of entangled pairs, the likes of which physicists have not yet seen. And that could be hugely useful for everything from quantum communication to quantum teleportation.That is still a long long ways from a Star Trek Transporter Room. But it is definitely a step in that direction. For those of you interested in some of the more technical details and a nice graphic RTWT.

Teleportation would require the conversion of mass to energy (as photons) and energy back to mass.
All the electricity used by the population of the US for a year could be made from about 2 tonnes of matter converted into energy assuming 100% efficiency.
Hence to teleport a human would need the disintergration of about 40 lbs of mass or 20 nuclear power plants working for a month.
Ergo, to ever teleport significant masses, we would have to have had developed HUGE new energy resources.
