    From Nature:


    Current commercial bits comprise around 1 million atoms. But in experiments physicists have radically shrunk the number of atoms needed to store 1 bit — moving from 12 atoms in 2012 to now just one. Natterer and his team used atoms of holmium, a rare-earth metal, sitting on a sheet of magnesium oxide, at a temperature below 5 kelvin.

    Far from a commercial viable product at 5 K degrees, but farther scientific advances could change that.

    An accompanying article:


    Even more impressively, they show that
    the atom’s magnetic state can be written and
    read using a scanning tunnelling microscope.
    The authors first apply a high voltage (above
    about 150 millivolts) to the microscope tip to
    flip the atom’s spin — this is the writing pro-
    cess. Because the tip is magnetic, electrical
    conductance through the probed atom varies
    depending on the direction of the atom’s spin
    with respect to the magnetization of the tip.
    The authors then read the atom’s magnetic
    state by measuring this conductance. They
    show that if low voltages (below about 75 mV)
    are used, the magnetic state can be stable for
    many hours.

    I don't know if either of these articles are paywalled or not, because I have my system to log in to my subscriptions.

    Hard to get more dense data storage than this, until we do it in 3D instead of 2D.

    Thank you my dude. I was reading about it yesterday. It's still expensive stuff, but as proof of concept, looks nice

    Damn, I'd be a little freaked out right now if I were you, nono, tbh...

    Where can I find this, "nuclear hard drive"? I'll take 7 to go alongside my 36 1440p IPS monitors all in side by side lanscape mode running Excel
