In this paper, a binary full adder circuit is designed with eight quantum rings where each ring is threaded by a magnetic flux phi0/2. The quantum rings are divided into two categories with four rings connected to each other in parallel. They are attached symmetrically to two semi-infinite one-dimensional metallic electrodes, and three gate voltages are applied as three inputs of the full adder. The Hamiltonian of the system is approximated by the tight-binding method, and the calculations are performed by using Green’s function formalism. The conductance-energy and current-voltage characteristics are obtained for different values of applied gate voltage. The results show this quantum circuit behaves as a binary full adder.
