A novel method for designing odd base quantum half adder

For various reasons in recent years the interest in building quantum computers has increased gradually. To do the calculations in quantum computer we need quantum arithmetic logic unit (ALU). The building block of quantum ALU is quantum adder. In quantum computer multivalued logic is possible. In this paper a generalized circuit has been proposed to build odd base multivalued quantum half adder. A novel approach has been taken to minimize the total no. of gates. Muthukrishnan-Stroud gates and quantum shift gates have been combined to achieve the minimal circuit.
