....back into place by a second reset gate after each use of the switch. In an actual experiment that approximates this design, Eigler et al. created a bistable atom switch with the aid of an STM. In their switch, a xenon atom transfers back and forth between the tip of an STM and a substrate [128], 160] The location of this switching atom greatly affects the tunneling current that flows from the STM tip to the GOLDHABER GORDON et al.

....of quantum computation which these physical systems can perform. I believe that other microscopic systems which have been discussed for quantum computation, for example the Notre Dame logic gate [10] operating by the hopping of electrons from one quantum dot to another) or the atom switch [11] (operating by the hopping of a single atom from one site on a crystal surface to another) are similarly problematic; although I know of no measurements of t OE in these cases, I expect that it is similarly short. Even these systems will be too classical [12] As the table shows, there are ....
