In recent years, reversible logic circuits have applications in the emerging field of digital signal processing, optical information processing, quantum computing and nano technology. Reversibility plays an important role when computations with minimal energy dissipation are considered. The main purpose of designing reversible logic is to decrease the number of reversible gates, garbage outputs, constant inputs, quantum cost, area, power, delay and hardware complexity of the reversible circuits. This paper reveals a comparative review on various reversible logic gates. This paper provides some reversible logic gates, which can be used in designing more complex systems having reversible circuits and can execute more complicated operations using quantum computers. Future digital technology will use reversible logic gates in order to reduce the power consumption and propagation delay as it effectively provides negligible loss of information in the circuit.

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[Formula: see text]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.
