Quantum computers for the efficient simulation of physical systems are emerging today. Effect of Spin on Quantum Dots (QDs) paved the way for QCA. Quantum-dot cellular automata (QCA) have a simple cell as the basic element. The cell is used as a building block to construct gates and wires.Reversible logic has extensive applications in quantum Computing. Reversible logic is widely being considered as the potential logic design style for implementation in modern nanotechnology and quantum computing with minimal impact on physical entropy. Reversible gates such as Fredkin and DKG gates can be of great use for the implementation of the logic designs. Recent advances in reversible logic allow for improved quantum computer algorithms and schemes for corresponding computer architectures.In this paper, a design constructing the hybrid adder -Subtractor based on reversible logic gates as logic components using QCA is proposed. By using reversible logic gates instead of using traditional logic gates such as AND, OR, XOR, NOT, a Hybrid reversible Adder -Subtractor whose function is the same as the traditional Adder and Subtractor are designed and compared with the functioning of DKG gate based adder-subtractor. The simulation results shows that higher speed, smaller size and lower power consumption can be achieved with the proposed HAS system. GeneralTermDesign

“…One of the hurdles in the development of super fast computing system is energy dissipation. In reversible computing, the relation between energy dissipation and computing at logic level [17] is calculated. Reversible computation is established at logic level by a one to one onto mapping between the input and the output states of a circuit.…”

Synthesis of reversible sequential circuits is a very new research area. It has been shown that such circuits can be implemented using quantum dot cellular automata. Other work has used traditional designs for sequential circuits and replaced the flip-flops and the gates with their reversible counterparts. Our earlier work uses a direct feedback method without any flip-flops, improving upon the replacement technique in both quantum cost and ancilla inputs. We present here a further improved version of the direct feedback method. Design examples show that the proposed method produces better results than our earlier method in terms of both quantum cost and ancilla inputs. We also propose the first technique for online testing of single line faults in sequential reversible circuits.
