Rapid progress in the field of nanotechnology includes using quantum dot-cellular automata (QCA) as a replacement for conventional transistor-based complementary metal oxide semiconductor (CMOS) circuits construction nano-circuits. Due to ultra low thermal dissipation, rapid clocking, and extremely high density, QCA is rapidly growing nanotechnological inhibit effect transistor (FET)-based circ...

We examine the energy dissipated by a two-state quantum system during switching operation when interacting with thermal environment. For an isolated system, excess decreases exponentially time. classically damped systems, dissipation linearly model coupled to environment using Lindblad equation for density matrix. rapid switching, exponential adiabaticity holds. slow enough damping from bath yi...

Quantum-Dot Cellular Automata (QCA) is a transistor-less technology. In QCA, Columbic repulsion between electrons in the quantum dots makes data transfer possible. This paper presents design of flip flops using proposed Rotated-Normal Cells with Displacement (RND) inverter and cell interaction method. The SR latch, Flip Flop (FF), D FF, T FF are developed QCA. gives total average energy dissipa...
