Quantum Cellular Automata (QCA) is one of the leading technologies in the electronics industry. Using this technology, low power consumption, small sizes, high density, and high-speed structures are achieved. Since flip-flops are one of the most important parts of digital circuits, designing a structure with a smaller size and delay and more facilities are of great importance. In this paper, novel edge-triggered D flip-flops with reset and set abilities are proposed in QCA technology using a suitable D-latch. The proposed works are optimized in terms of size and delay. Simulation results show that the proposed designs have a fewer number of cells and complexity, smaller area and less delay than similar cir- cuits. The final proposed circuits have also set and reset abilities which rarely can be seen in previous designs. In addition, the proposed edge-triggered D flip-flops with set and reset abilities are designed in the coplanar method which facilitates the manufacturing process.
