 June 2002 issue SpintronicsMicroelectronic devices that function by using the 
spin of the electron are a nascent multibillion-dollar industry--and may lead 
to quantum microchipsBy David D. Awschalom, Michael E. Flatté and Nitin Samarth 
 As rapid progress in the miniaturization of semiconductor electronic devices 
leads toward chip features smaller than 100 nanometers in size, device 
engineers and physicists are inevitably faced with the looming presence of 
quantum mechanics--that counterintuitive and sometimes mysterious realm of 
physics wherein wavelike properties dominate the behavior of electrons. 
Pragmatists in the semiconductor device world are busy conjuring up ingenious 
ways to avoid the quantum world by redesigning the semiconductor chip within 
the context of "classical" electronics [see "A Vertical Leap for Microchips," 
by Thomas H. Lee; Scientific American, January]. Yet some of us believe that we 
are being offered an unprecedented opportunity to define a radically new class 
of device that would exploit the idiosyncrasies of the quantum world to provide 
unique advantages over existing information technologies
