Quantum-dot cellular automata (QCA) is a nanoscale technology to design digital circuits in nano-measure which acts based on electron’s interaction. The technology of collecting, processing and distributing information is growing rapidly, but the growth in demand for advanced methods in data processing has always been greater than the speed of growth of these technologies. Hence, computer networks play an important role in providing a resource sharing and facilitating user communications. The circuit-switched network is one of the main components for sending input signals between different users within the network. In this paper, a minimal and optimal design of the circuit-switched network is presented at a single level in QCA. The proposed design is studied and compared with existing designs in terms of fault tolerant under stuck-at 0 and 1. There is also a physical analysis for the proposed circuit-switched network.
