Quantum-dot cellular automata (QCA) are a promising nanotechnology to implement digital circuits at the nanoscale. Devices based on QCA have the advantages of faster speed, lower power consumption, and greatly reduced sizes. In this paper, we are presented the circuits, which generate random numbers in QCA.  Random numbers have many uses in science, art, statistics, cryptography, gaming, gambli...

One of the major problems in designing highly compact integrated circuits is power consumption circuits. Therefore, several technologies have been introduced to overcome facing MOSFET technology. these Quantum-Dot Cellular Atomata (QCA), which has advantages. In this paper, we focus on computational logic gates based T-Latch circuit. T-latch basis many circuit arithmetic unit (ALU). The propose...
