Abacus Computation

Page 3 of 4


Computation using the atomic abacus will not require the use of fingers to do so. Since it is so small, it requires a state of the art technology that will push the beads and then do the calculation. This can be done by using the ultrafine tip of a STM (Scanning Tunneling Microscope).

STM is a needle which has a conical shape that would be used in terminating a single atom at its very tip. The result of the calculation using the STM will be visible only by operating it in image mode.


The individual molecules, which are the beads of the atomic abacus if approached by the tip of the STM, then the beads, will be pushed back and fourth in a controlled and précised manner in order to count from 0 to 10 and it is done with the help of a probe.


In a conventional atomic abacus which was recently developed in Switzerland, this probe is made of hard diamonds. This diamond probe is sharpened at the tip with a size of an atom, which makes it to just move the bucky balls for the computation purpose. The molecules are moved in the same way as the beads are moved in an ordinary abacus.
