Magnetic Microchips

I've been real busy lately and haven't done much surfing for my Quantum fascination. I did however find something that is pretty exciting when doing my blog role. I see that a bunch of researchers are now able to do boolean operations on nanoscale magnetic “islands” with the 1's and 0's of binary code (link). This is a big news for nerds and here is why:

Because the chip has no wires, its device density and processing power may eventually be much higher than transistor-based devices. And it won't be nearly as power-hungry, which will translate to less heat emission and a cooler future for portable hardware like laptops.

Computers using the magnetic chips would boot up almost instantly. The magnetic chip's memory is nonvolatile, making it impervious to power interruptions, and it retains its data when the device is switched off.

The magnetic architecture of the chip can be reprogrammed on the fly and its adaptability could make it very popular with manufacturers of special-purpose computing hardware, from video-game platforms to medical diagnostic equipment.

Well this is one step farther from transistor based computing, but I'm not going to get too excited until qubits are figured out.
