>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. ....................
