Abstract:

In this study a novel nanometric fault tolerant quantum and reversible binary coded decimal adder is proposed. Reversible logic has found emerging attentions in optical information processing, quantum computing, nanotechnology and low power design. BCD Adder is a combinational circuit that can be used for the addition of two numbers in BCD arithmetic's. The proposed reversible BCD adder has also parity preserving property. It is better than all the existing counterparts. The proposed circuit is optimized. It is compared with the existing circuits in terms of number of constant inputs, number of garbage outputs, quantum cost and hardware complexity. All of the parameters are improved dramatically. It is to be noted that all the circuits have nanometric scales.
