Quantum-dot Cellular Automata (QCA) is a transistor-less technology in which the information passes using a technique that requires the breeding of a polarization state from one circuit element to another, and computations take place without current. The reversible logic circuits potentially overcome the extreme power dissipation problem in CMOS circuits in quantum computing. In any computation system, the core part of the system is the Arithmetic and Logic Unit (ALU). This paper proposes a QCA technology-based reversible ALU using the Peres and Double Peres gates and implements multilayer architecture. It performs 29 operations, including logic operations, addition, increment, and subtraction. This ALU contains 199 cells with 2.5 clocks of latency. In comparison to existing research, the proposed multilayer ALU architecture improves the cell count and area by 20% and 66%, respectively. The total energy dissipation of the design is \(8.24e-02 eV\). QCA Designer 2.0.3 is used to simulating the proposed ALU architectures.

“…There are four clock phases: switch, hold, release, and relax, as shown in Fig. 2 10 , 11 . In the first phase, the QCA cells will get depolarized as tunnelling potential barriers are low.…”

The article introduces a revolutionary Nanorouter structure, which is a crucial component in the Nano communication regime. To complete the connection, many key properties of Nanorouters are investigated and merged. QCA circuits with better speed and reduced power dissipation aid in meeting internet standards. Cryptography based on QCA design methodologies is a novel concept in digital circuit design. Data security in nano-communication is crucial in data transmission and reception; hence, cryptographic approaches are necessary. The data entering the input line is encrypted by an encoder, and then sent to the designated output line, where it is decoded and transferred. The Nanorouter is offered as a data path selector, and the proposed study analyses the cell count of QCA and the circuit delay. In this manuscript, novel designs of (4:1)) Mux and (1:4) Demux designs are utilized to implement the proposed nanorouter design. The proposed (4:1) Mux design requires 3–5% fewer cell counts and 20–25% fewer area, and the propsoed (1:4) Demux designs require 75–80% fewer cell counts and 90–95% fewer area compared to their latest counterparts. The QCAPro utility is used to analyse the power consumption of several components that make up the router. QCADesigner 2.0.3 is used to validate the simulation results and output validity.
