ABSTRACT:
In an atomic switch, opposite ends of an atom wire are connected to an input and output, and a switching gate is connected to a switching power supply. An input signal is outputted when a switching atom is connected to the atom wire, whereas an input signal is not outputted when the switching atom is moved to disconnect from the atom wire. There are provided an atom wire having a plurality of atoms arranged in a line or in a plurality of lines, in a ring shape, or in a curved line, and a switching gate made of an atom wire. The atom wire is switched by the field effect of the switching gate.
