Physicists Discover How To Teleport Energy

Posted by ScuttleMonkey on from the scott-me-up-beamy dept.

MikeChino writes "A physicist at Tohoku University in Japan has figured out how to teleport energy from one point in the universe to another. The technique is based upon prior research that shows it's possible to teleport information from one location to another, and involves making a measurement on each [of] an entangled pair of particles. The measurement on the first particle injects quantum energy into the system, and then by carefully choosing the measurement to do so on the second particle, it is possible to extract the original energy. Heady stuff, but essentially it means that you can inject energy at one point in the universe and extract it from somewhere else without changing the energy of the system as a whole."

    I don't understand what the hell is going on, but it seems to me that if you can send energy someplace faster than the speed of light, that could be used to transmit "information".

    In this case, you have to "measure" the particle in a particular way to retrieve the energy, and that way depends on what happened to the particle on the other side while the energy is being "pumped in" (so you cannot know in advance). So there needs to be an existing information channel to transmit the information on exact way of measurement that needs to be performed, which obeys the usual rules.

    So "teleport" is misleading since you cannot transmit power any faster than information, and that has to travel at the speed of light at most (as far as we know (this week anyway) anyway).

    Sorry to burst your bubble but you can't transmit information faster than light.

    Period.

    Unless the theory of relativity turns out to be incomplete as a model of the universe. But that's almost certainly impossible as all our previous theories have proved to be perfect in every respect and this one is sure to too.

    Period*.

    *: As long as current observations that the universe is causal are not falsified.

    Fixed that for you.
