Dataset demonstrating the temperature effect on average output polarization for QCA based reversible logic gates.

Quantum-dot cellular automata (QCA) is a developing nanotechnology, which seems to be a good candidate to replace the conventional complementary metal-oxide-semiconductor (CMOS) technology. In this article, we present the dataset of average output polarization (AOP) for basic reversible logic gates presented in Ali Newaz et al. (2016) [1]. QCADesigner 2.0.3 has been employed to analysis the AOP of reversible gates at different temperature levels in Kelvin (K) unit.

Value of the data

Reversible gates are the basic building block of reversible logic systems. This dataset helps researcher to enhance the performance and reliability of digital systems.

The presented data analysis can support the researchers to find the maximum operating temperature of a particular QCA design.

The proposed dataset can be used to design robust and lossless arithmetic logic unit (ALU) in quantum computers.

Experimental design, materials and methods

AOP analysis

The average output polarization is declined gradually with the increment of temperature [2]. At any specific temperature, the AOP of an output cell can be calculated by simply taking the difference between maximum polarization and minimum polarization and dividing the result by two.

To analysis the AOP, QCADesigner tool ver. 2.0.3 [3] has been used with coherent vector simulation engine. The following default parameters have been considered. The default parameters are listed as: QCA cell size = 18 nm, diameter of quantum dots = 5 nm, number of samples = 50,000, relative permittivity = 12.9, convergence tolerance = 0.001, radius of effect = 65 nm, clock low = 3.8e−23 J, clock high = 9.8e−22 J, clock amplitude factor = 2.000, layer separation = 11.5 nm and maximum iterations per sample = 100. The graphical representation of AOP of different reversible logic gates presented in [1] is illustrated in Fig. 1.
