Punctuating 30 years of nanotechnology research, scientists from IBM Research (NYSE: IBM) have successfully demonstrated the ability to store information in as few as 12 magnetic atoms. This is significantly less than today’s disk drives, which use about one million atoms to store a single bit of information. The ability to manipulate matter by its most basic components – atom by atom – could lead to the vital understanding necessary to build smaller, faster and more energy-efficient devices.

Interesting news.

A few years ago, I did some reading on Scanning Tunneling Microscopes (STMs), and how they can detect and manipulate individual atoms. Linked below are two different locations at the source website of the images included in my post. The source has more fun images like the ones in my post, none related to arranging computer bits or any of that. (©IBM)

Bye now.

I mean by changing and re-orienting magnetic moment maybe they could achieve not only 1 and 0 but also its superposition.
The research seems to have determined the minimum number of atoms with identical spin orientations required to hold data stable in a binary system. Qubits are not used this way.

^ They are. Qubits could use all 3 spin orientations. If you ain't bothered to read it's not my problem.
