In present years, reversible logic has attained importance in many applications in the field of Quantum Computing, Nanotechnology, Low Power CMOS Design, Cryptography, etc. Without reversible logic, it is not possible to realize quantum computing. Code converters are combinational circuits which are used in digital systems designed to enhance the security of data and to decrease the hardware complexity. This paper presents a design for the reversible gray to binary code converter circuit. The main aim in the reversible logic design is to minimize the number of reversible gates used and the garbage output produced. The proposed design is compared to the existing designs in terms of parameters such as reversible gates, constant inputs, garbage outputs, and quantum cost.
