“…However, unlike this work, they are normally presented apart. Islam , et al proposed a non‐reversible 4‐bit gray to 4‐bit binary and a 4‐bit binary to 4‐bit gray [15]. They used fewer QCA cells than previous work by implementing the logic with the same XOR gate we use in our devices.…”

This study describes the first Gray-code adder architecture, without the need to transform the Gray code into binary code, using the quantum-dot cellular automata (QCA). This device is a widely used resource for machine communications, counters, and encoders. QCA is a possible alternative to the current integrated circuit [complementary metal oxide semiconductor (CMOS)] due to its nanometric scale and very low-power consumption. In a bottom-up approach, the authors first describe and present the architecture of an important building block that composes the Gray-code adder, the parity generator, and then describe the full architecture. Besides being essential in the proposed adder, the parity generator is also important for error-checking and construction of other devices and widely used in communications. They demonstrate the functionality, test, and validate the proposed architectures using the QCADesigner simulator. If QCA consolidates as a possible CMOS substitute, this study can impact the design of future components that uses Gray-code and parity generator, such as embedded digital communications systems that will benefit from the low-power consumption of the QCA technology.

Quantum-dot cellular automata (QCA), due to its unique characteristics like low power consumption, nanoscale design, and high computing speed is considered as an emerging technology, and it can be used as an alternative for CMOS technology in circuit design for quantum computers in the near future. XOR gate has many applications in the design of digital circuits in QCA. In this paper, an efficient novel structure of XOR gate is proposed in QCA. Also, a novel 1-bit comparator circuit, 1-bit full adder, binary to gray and gray to binary convertor code based on the proposed XOR is designed and simulated using QCADesigner 2.0.3. The simulation results demonstrated that the proposed structures provide improvements compared to previous works in terms of QCA cells count, area, and circuit cost.
