Nano-router design for nano-communication in single layer quantum cellular automata

Abstract

Quantum dot Cellular Automata(QCA) is a new electronics paradigm for information technology and communication. It has been recognized as one of the revolutionary nano-scale computing devices. In this work, we have selected few basic gates using QCA to develop a 4: 4 router. The main function of this design is to transfer information from four input ports through a DEMUX and receive this information at the four different receiver port. The information that has been provided is being routed via crossbar in the present study. We use a parallel to serial converter to receive the information at the receiver port. This router has been implemented with less clock delay and less QCA, which results into an efficient router comparing to any other router. This Nano-router can be used for distributed computing. The QCA Designer Software is used for designing and simulating the circuits.
