Macroscopic entanglement

  1. Feb 9, 2016 #1
    I came across an quote from a physicist so I wanted your opinion.
    Most physicists, Walmsley says, believe that quantum entanglement is a property present in all objects in our macro world; we just don't see it happening. "In the everyday environment, objects are connected to other objects," he says. "They're sitting on the floor, wafting in the wind, and those connections are ways in which information and energy can leak out of one system into another." So objects lose their entanglement quickly. By using super-speedy technology, this team caught the diamonds acting entangled before environmental interactions overcame the effect.

    Are objects in the macroscopic world really entagled or did he meant that they aren't in principle due to enviroment but it is possible to induce it in experiments?

    Do you have a source?

    There is no reference to the original paper in that Popular Mechanics article, and a search on arXiv on Walmsley's papers didn't turn up anything that seems to describe such an experiment (but he is very prolific, so I might have overlooked it).

    This could very well be another example of a science journalist garbling things up completely.

    I guess he just meant that all macroscopic objects have the potential for entaglement in his first sentence, and in his second that interaction prevents it in our scale of everyday life.
