A new spin on computing

Posted on July 2nd 2011 in Features with 1 comment

Spin, as anyone who has ever heard Alistair Campbell speak, is a tricky thing to figure out. Quantum spin – a property many subatomic particles have – is equally confounding, but, if understood, could lead to a powerful new breed of computer technology called spintronics. Despite its name, quantum spin does not actually refer to a rotating ball such as the Earth. “The electron is not physically spinning around but it has a magnetic north pole and a magnetic south pole,” says Professor Philippe Jacquod, a researcher in spintronics at the University of Arizona. β€œIts spin depends on which pole…
