The links given by sbayne were very interesting reading.
One key mention I would bring back to illustrate the difficulty in transferring this to some common product is: "" in 2012, persistent spin helices of synchronized electrons were made to persist for more than a nanosecond "" from the WIKI link .
From the third link: "" theory predicts lifetimes of around a microsecond for pristine graphene, whereas experiment shows values ranging from tens of picoseconds to a few nanoseconds. ""
