As CMOS scaling faces a technological barrier in these days, novel design paradigms are being proposed to keep up with the ever growing need for computation power and speed. Most of these novel technologies have device sizes comparable to atomic and molecular scales. At these levels the quantum mechanical effects play a dominant role in device performance, thus inducing uncertainty. The wave nature of particle matter and the uncertainty associated with device operation make a case for probabilistic modeling of the device. As the dimensions go down to a molecular scale, functioning of a nano-device will be governed primarily by the atomic level device physics. Modeling a device at such a small scale will require taking into account the quantum mechanical phenomenon inherent to the device. The Quantum-Dot Cellular Automata (QCA) is a radical nanotechnology, which works at nano-scale. In this paper, an optimal design of 2n:1 Multiplexer (MUX) is presented. A new approach has been devised to implement efficient digital logic gates using the proposed 2n:1 multiplexer. To verify the functionality of the proposed structures and Boolean proofs are performed. A detailed comparison, structural evaluation of the proposed multiplexer with recently robust designs is analyzed. This evaluates the performance of the proposed multiplexer in terms of cell count, area clock delays as compared to traditional approaches. The usefulness of exhibited designs has been performed in QCADesigner form 2.0.3 tool
