Reversible logic gates are essential for quantum computing and low-power digital circuits as they enable the recovery of input signals from output signals, thereby minimizing energy dissipation. This ...

This paper proposes a new design of quantum-controlled adder/subtractor (QCAS) with efficient quantum criteria like delay, quantum cost, number of ancilla and of garbage outputs. We propose a quantum ...

In order to generate the full adder and subtractor, multiple subcircuit cells were mixed and distributed in two different wells ().One well represents the solution (S) or difference (D) and a second ...
