Researchers Store One Bit of Information in Just 12 Atoms

submitted by Skeeve

1 decade 2 years 4 months 1 week ago

IBM Research - Almaden physicist Andreas Heinrich explains the industry-wide need to examine the future of storage at the atomic scale and how he and his teammates started with 1 atom and a scanning tunneling microscope and eventually succeeded in storing one bit of magnetic information reliably in 12 atoms.

I wonder what the next step would be after they perfect this.

You can not get smaller than an atom and have a form of control.

Currently our technology is only able to operate on 2 extreme levels,ie the magnetized and demagnetized states representing zero and one.But in the future we will be able to program these atoms to more than 2 distinctive states.Like demagnetized representing 0,1x magnetized representing 1,2x magnetized representing 10 and so on.

There was an interesting paper recently on 4 atom wide wires... It is crazy that fluctuations don't kill their device.

IBM also submitted, by far, the largest number of patents for 2011 than any other firm in the world. For the 19th year in a row.
