Quantum Cost Efficient Reversible BCD Adder for Nanotechnology Based Systems

Md. Saiful Islam, Mohd. Zulfiquar Hafiz, Zerina Begum

Reversible logic allows low power dissipating circuit design and founds its application in cryptography, digital signal processing, quantum and optical information processing. This paper presents a novel quantum cost efficient reversible BCD adder for nanotechnology based systems using PFAG gate. It has been demonstrated that the proposed design offers less hardware complexity and requires minimum number of garbage outputs than the existing counterparts. The remarkable property of the proposed designs is that its quantum realization is given in NMR technology.
