When it comes to spintronics, there may be some room in the middle

Spintronic devices that utilize the spin degree of freedom of a charge carrier to store, process or transmit information, may be better performers than their traditional electronic counterparts if special properties of "spin" are exploited in the design. I review here the example of "single spin logic" which follows this principle. It can reduce power dissipation by several orders of magnitude and is the progenitor of today's spin based quantum logic gates. These devices are far easier to realize than "quantum computers", while much more likely to exhibit the advantages touted for spintronics than mere spin-based analogs of conventional transistors.
