The CMOS faces challenges related to the increment in leakage-current power-consumption. QCA is a promising alternative overcome these successfully. On other hand, reversible logic plays significant role quantum-computing. Keeping this technique mind, conservative-reversible flip-flops and counter are explored here which will bring computing together single-platform. In synthesizing, reversible-conservative-quantum-cellular-automata (R-CQCA) proposed. proposed D, T, JK dual-edge master-slave advocate an improvement of 20%, 46.6%, 50%, 36.66% respectively than its counterpart quantum-cost. Further, 100% fault-coverage by stuck-fault framed R-CQCA, can be useful for tester maintain data-integrity. Also, R-CQCA layout implemented QCA, achieve some parameters such as cell-complexity 177, leakage-energy-dissipation 0.1055 eV, size 0.24 µm2. Moreover, better FRG, RM, PPRG MX-cqca regarding QCA-primitives reported here.
