A novel parity preserving reversible binary-to-BCD code converter with testability of building blocks in quantum circuit

Abstract

The reversible logic circuit is popular due to its quantum gates involved where quantum gates are reversible and noted down feature of no information loss. In this paper, parity preserving reversible binary-to-BCD code converter is designed, and effect of reversible metrics is analyzed such as gate count, ancilla input, garbage output, and quantum cost. This design can build blocks of basic existing parity preserving reversible gates. The building blocks of the code converter reversible circuit constructed on Toffoli gate based as well as elemental gate based such as CNOT, C-V, and C-V+ gates. In addition, qubit transition analysis of the quantum circuit in the regime of quantum computing has been presented. The heuristic approach has been developed in quantum circuit construction and the optimized quantum cost for the circuit of binary-to-BCD code converter. Logic functions validate the development of quantum circuit. Moving the testability aim are figured in the quantum logic circuit testing such as single missing gate and single missing control point fault.
