The prediction and forthcoming of a quantum computer into the real-world is the much gained research area over the last decades, which initiated the usefulness and profit of reversible computation because of its potentiality to reduce power consumption in designing arithmetic circuits. In this paper, two design approaches are proposed for the design of a reversible Binary-Coded-Decimal adder. The first approach is implemented and realized from reversible gates proposed by researchers in the technical literature capable of breaking down into primitive quantum gates, whereas the second approach is realized from the existing synthesizable reversible gates only. Parallel implementations of such circuits have been carried out through the proper selection and arrangements of the gates to improve the reversible performance parameters. The proposed design approaches offer a low quantum cost along-with lower delay and hardware complexity for any n-digit addition. Analysis results of proposed design 1 show appreciable improvements over gate count, quantum cost, and delay by at least 9 %, 17 %, and 26 % respectively, whereas, the proposed design 2 show that the results significantly improve the parameters (gate count, quantum cost, and delay) by at least 45 %, 33 %, and 50 % respectively compared to existing counterparts found in the literature.
