Single Photons Bounced Off Orbiting Satellite

KentuckyFC writes "If we're ever going to benefit from the perfect security of quantum communication, we're going to need ways of transmitting entangled photons around the globe and certainly further than the current record of 144km through the atmosphere. Anton Zeilinger at the University of Vienna and colleagues have taken an important step towards this by bouncing individual photons off the Ajisai geodetic satellite (essentially a space-based disco ball) which is orbiting at 1400km. The group says the experiment is an important proof of principle for satellite-based quantum communications."

    Fuck. This site is unreadable at this point. This is the first time I've been back in two months. I was hoping that it might have been fixed by now.

    I never expected Slashdot to succumb to javascript. I am very disappointed. I suppose I could try Lynx and see if it can retrieve a readable page from slashdot, but I don't expect so.

    I'll check back in another two months to see if Slashdot has recovered from this devastating design decision. (I see the lower numbers of comments on the stories now indicate that I am not the only one who feels this way)

      There's a check box in the preferences, genius.

      If you create an acct, (as I have) you can set it to the old version in your prefs. I hate the new layout as well.
