“…Since quantum computing is inherently reversible and information is not lost in reversible computations, the use of quantum gates prevents power dissipation [11,12]. Quantum gates implement permutation functions and have the same number of outputs and inputs [13][14][15][16]. Fan-out and feedback from output to input are prohibited when designing quantum reversible circuits [17].…”

Designing conventional circuits present many challenges, including minimizing internal power dissipation. An approach to overcoming this problem is utilizing quantum technology, which has attracted significant attention as an alternative to Nanoscale CMOS technology. The reduction of energy dissipation makes quantum circuits an up-and-coming emerging technology. Ternary logic can potentially diminish the quantum circuit width, which is currently a limitation in quantum technologies. Using qutrit instead of qubit could play an essential role in the future of quantum computing. First, we propose two approaches for quantum ternary decoder circuit in this context. Then, we propose a quantum ternary multiplexer and quantum ternary demultiplexer to exploit the constructed quantum ternary decoder circuit. Techniques to achieve lower quantum cost are of importance. We considered two types of circuits, one in which the output states are always restored to the initial input states and the other in which the states of the output are irrelevant. We compare the proposed quantum ternary circuits with their existing counterparts and present the improvements. It is possible to realize the proposed designs using macro-level ternary gates that are based on the ion-trap realizable ternary 2-qutrit Muthukrishnan–Stroud and 1-qutrit permutation gates.

“…The quantum computing is very much promising field of engineering and technology due to low power dissipation, high speed operation. The very essential parameters of the design and implementation for reversible logic circuits are the quantum cost, delay and garbage outputs [1][2][3][4]. The quantum cost of a reversible logic gate is the numbers of 1×1, 2×2 quantum gate such as NOT, Controlled-V, Controlled-V + and CNOT gates [2,[5][6][7].…”

In this paper the authors have proposed a new 3×3 reversible gate and also proposed the reversible combinational logic circuits with better optimized quantum cost, garbage outputs and delay. The proposed new reversible logic gate is used to design of reversible 1-bit comparator circuit and realization of different logic functions such as NOT, AND, NAND, OR, NOR, XOR, NXOR. The proposed new reversible logic gate is represented by quantum implementation. The quantum cost of proposed gate is 4. The quantum cost, garbage output and delay of proposed reversible 1-bit comparator circuit are 6 which is better w. r. t. previously reported results.
