2021年11月1日 · The reversible bistate joint NIMPLY (BJN) gate is a modified Toffoli gate that has a quantum cost of five. The motivation behind the design of an optical BJN gate is its functionality as a universal logic gate.

2022年12月27日 · To exploit quantum physics in many application fields, circuit design using reversible gates is a crucial task. In this paper, quantum implementation of three-input/three-output (3 × 3) reversible gates is presented. The functional matrices of most of the gates are presented for the first time in this paper.

Reversible Gates are circuits in which number of outputs is equal to the number of inputs and there is a one to one correspondence between the vector of inputs and outputs[8-10]. It not only helps us to determine the outputs from the inputs but also helps us to uniquely recover the inputs from the outputs.

2020年11月23日 · In this study, a novel design of a reversible priority encoder based on QCA is proposed. The basic building blocks for the design are Toffoli and BJN gates. The proposed design is verified by the QCA designer simulator. The performance analysis of the reversible priority encoder is performed based on the simulation results.

Reversible circuit for carry lookahead generator and its realization in QCA have been reported in this paper. To achieve the proposed design, Toffoli gate based reversible AND operation and BJN gate based reversible OR operations have been used. The designs are verified by comparing the simulation outcome with the theoretical values.
