The big step they're working on is using a magnetically charged material to be able to use the electrons at room temperature. Prior to this, the electrons needed to be cooled below -120 Celsius in order for their magnetic properties to take hold. Slashdot covered the discovery of this material in 2004 as well as a follow up story and also research on possibilities about using it for quantum computing. Now MIT is working on implementing its use in processors but there still are some barriers to overcome. Spintronics has also been applied to data storage and memory."
