“IBM MAKES IT POSSIBLE FOR DATA TO BE STORED ON INDIVIDUAL ATOMS”

Scientists at IBM have figured out a way to encode data on individual atoms, which would be the most compact information storage ever achieved. The common thinking amongst hardware designers is that as digital storage continues to get smaller, the basic unit of information storage is also shrinking as well. Eventually the amount of atoms required to store data will become so small that storing a single bit will someday require only a single atom. This is what IBM researchers have brought to life. Using holmium atoms embedded on a magnesium oxide base and a scanning tunnelling microscope, they have managed to encode data on an atom and managed to read the same data right after. Since the atom has a special characteristic called magnetic bistability, it has two different magnetic spins. Using the microscope, the researchers applied about 150 millivolts at 10 microamps to the atom. This electricity acted as a sort of lightning strike that caused the atom to switch its magnetic spin state (one state represents 1, the other 0 in binary code). "To demonstrate independent reading and writing, we built an atomic-scale structure with two Ho bits, to which we write the four possible states and which we read out both magnetoresistively and remotely by electron spin resonance. The high magnetic stability combined with electrical reading and writing shows that single-atom magnetic memory is indeed possible,“ the abstract read.

As the annual tech-fest known as the Consumer Electronics Show gets underway, it’s looking like it will be attack of the drones. Here’s hoping a brave new world includes doughnuts.
