Nanotechnology + Superconductivity = Spintronics

karvind writes "Spintronics is a nanoscale technology in which information is carried not by the electron's charge, as it is in conventional microchips, but by the electron's intrinsic spin and if a reliable way can be found to control and manipulate the spins spintronic devices could offer higher data processing speeds, lower electric consumption, and many other advantages over conventional chips--including, perhaps, the ability to carry out radically new quantum computations. PhysOrg is reporting that University of Notre Dame physicist Boldizsar Janko and his colleagues have found a way to achieve this control using a magnetic semiconductor, insulator and superconducting material stack of thicknesses of order of few dozen nanometers. IBM and Stanford are also looking into spintronics."

Spintronics and the Chinese Threat

[Anonymous Coward]

We Americans should keep this technology secret. It could prove a boon to military communications. If the Chinese had access to this technology, they would quickly integrate it into their space-born weapons systems.
