“If you take a single atom, you have to look at quantum mechanics when you describe its behavior,” he said in an interview. “As you make the (system) bigger and bigger, several iron atoms start talking to each other, and at some point you can ignore all of this quantum behavior and just think of them as a classical magnetic structure.” It turns out that point is around 12 atoms big.
Imagine 1000 cores running at 1Thz = 1Phz (?). This is insane. With the combined tech we could begin simulating realistic virtual/simulated realities, unbiased rendering in real-time, the possibiltiies....

The nano magnets are only stable at a chilly 5 degrees Kelvin, or -450 degrees F.
Moreover, Dr. Heinrich said, smaller groups of atoms begin to exhibit quantum mechanical behavior — simultaneously existing in both “spin” states, in effect 1 and 0 at the same time. In theory, such atoms could be assembled into Qbits — the basic unit of an experimental approach to computing that might one day exceed the capabilities of today’s most powerful supercomputers.
Andreas Heinrich, the lead investigator into atomic storage at IBM Research Almaden and an author on a new paper describing the teeny bit. The team was interested in the transition from quantum to classical behavior, he said.
