  • Einstein’s “spooky action” goes massive!

    The elusive quantum mechanical phenomenon called entanglement has now been made a reality in objects almost macroscopic in size. Results published in Nature show how two vibrating drumheads, the width of a human hair, can display the spooky action.

    In 1935, Einstein observed that quantum mechanics, the then recently developed fundamental theory of nature, implies the existence of a “spooky action at a distance”, which soon became known as “entanglement”. It allows objects to affect each other across arbitrary distances without any direct interaction. The phenomenon defies both classical physics and our common-sense understanding of reality.

    For long it was considered nonsensical that entanglement could occur between objects larger than atoms or molecules.

    A team led by Professor Mika Sillanpää at Aalto University Department of Applied Physics have now proved otherwise. Their results have been published in Nature, the most esteemed scientific journal in the world.

    In their laboratory measurements, the researchers managed to bring two distinct and moving objects, nearly visible to the naked eye, into an entangled quantum state where they feel each other through the “spooky action” with which Einstein was famously uncomfortable . The objects in the experiments were two vibrating drumheads fabricated from metallic aluminium on a silicon chip. The drumheads are truly massive and macroscopic compared to the atomic scale: their diameter is similar to the width of a thin human hair.

    Up next, faster than light communication.

    Maybe this is why we don't hear alien dance radio?

    You cant control it and hence can't use it for FTL communication I'm afraid

      Other people do what they can, I do what I want.

      At least the article plays with the idea.

        all this "faster than light" is just a misinterpretation.
        macroscopic example.
        let we have a piece of paper. let we tear it in two pieces. Edge of one piece copies an edge of another. we seal this pieces in two envelopes and send one to finland to PEMM, and another one to flamming_python.
        and.
        without opening his envelope noone could say how looks his torn edge. But if someone has opened his envelope, he will IMMEDIATELY know how looks the edge of his vis-s-vis. and this IMMEDIATELY is interpreted as "above light speed".
        but in reality, if PEMM has opened envelope, he must send to Python the information, he discovered, and send it with a speed BELOW than speed of light(kinda via email).
        finally - your knowledge about result of some experiment in some world point, does not mean that you can communicate with this point faster than speed of light.

          Stop it with your logic man.

          We don't like that kind of thing here in science section.
