As an interesting and significant research domain, reversible logic is massively utilized in technologies, including optical computing, cryptography, quantum computing, nanotechnology, and so on. The realization of quantum computing is not possible without the implementation of reversible logic, and reversible designs are presented mainly to minimize the thermal loss because of the data input bits lost in the irreversible circuit. Digital converters, as the most important logic circuits, are used to connect computing systems with different binary codes. This paper first proposes a new reversible gate called Reversible Noorallahzadeh − Mosleh Gate (RNMG). Then, using the proposed RNMG gate as well as existing NMG1, NMG6, and PG gates, three different designs of reversible Binary-Coded Decimal (BCD) to EX-3 code converter are proposed. Our results indicate that the proposed BCD to EX-3 code converters are superior to previous designs in terms of quantum cost. Moreover, the proposed converters are comparable or better than previous designs in terms of gate count, constant inputs, and garbage outputs. [ABSTRACT FROM AUTHOR]
