Dr. Sorin Dan CotofanaThe PhysOrg.com article Tunneling Electrons Do Math said
Using a novel computing paradigm involving counting single electrons, computer engineers have designed nano-sized circuitry that allows tunneling electrons to perform mathematical division calculations.
While other methods utilizing quantum mechanical behavior have been proposed to increase computing power, these techniques have yet to take full advantage of quantum mechanical properties on the nanoscale namely, high speed and low power consumption.
Cor Meenderinck, a PhD student in Computer Engineering, and Sorin Cotofana, an Associate Professor in Computer Engineering, from the Delft University of Technology in the Netherlands, have recently published their research on a quantum mechanical behavior called single-electron tunneling (SET) in IEEE Transactions on Nanotechnology. Building on their past SET paradigms that perform addition and multiplication operations, Meenderinck and Cotofana have presented three schemes that use tunneling electrons to quickly divide.
