Quantum-Dot Cellular Automata (QCA) provides low power, high device density and faster switching speed. Nano-scale communication devices with low power dissipation can be achieved based on QCA technology. Several Nanocommunication circuits like nanorouter, signal distribution network, parity generator, parity checker, user authenticator, pipeline architecture, data path selector have already been reported by the researchers. The application of QCA in designing the architecture for Nanocommunication system increases the device density and computational fidelity of the computational channels. Low power consumption of QCA is useful to resist against power analysis attack. Besides, the embedding procedure of reversible logic into QCA is also helpful to achieve lossless low power dissipated Nanocommunication devices. In this paper, the application of QCA in designing the architecture of nanocommunication networks have been discussed and explored. Besides, the embedding procedure of reversible logic into QCA and their uses in designing of nanocomputing devices are also illustrated.
