> Normally, to move electrons you apply a voltage and the
> electrons begin to flow. That is the basis of Ohm's Law:
> Electrical current equals voltage divided by resistance. 
>
> But a team of physicists from Stanford and the University of
> California-Santa Barbara (UCSB) report in the March 19 issue
> of the journal Science that they have invented a device that
> moves electrons without relying on voltage differences to push
> them around. 
>
> The device -- a "quantum electron pump" -- operates
> according to the laws of quantum physics, .........
>
> .....So the growing ability to create nanoscale structures
> has allowed researchers to create devices that operate
> according to the laws of quantum physics and so can exhibit
> radically new modes of operation. ....................
