Abstract In the cryptographic domain, quantum and its real-time hardware simulation make it easier to secure data during communication. Here, using quantum logic, a unique encryption technique called Reversible select, cross, and variation (RSCV) encryption and decryption, which involves swapping input data halves, is shown. In this article using IBM Q, we created a cryptographic encoder and decoder circuit design utilizing various quantum gates. Based on the encoder/decoder circuit, a simple nanocommunication framework is proposed. Further, to explore the application of the noise model, how to utilize this model to create noisy replicas of these quantum circuits to research the impacts of noise that occur for actual device output is shown. To reduce measurement mistakes, measurement calibration is performed using qiskit ignis model. Preparing all 2n basis input states and calculating the likelihood of counting in the other basis states are the key concepts. The percentage improvement we achieved is 40%, 30%, and 30%, respectively, compared to earlier ones, in RSCV encryption, decryption, and RSCV cryptographic communication architecture for fake provider noise error model. It is feasible to adjust the average outcomes of an additional interesting experiment using these calibrations.
Quantum technology application is a rapidly developing discipline in future-generation research. It has grown its appeal due to several unique aspects which cannot be encountered in classical domains. Quantum properties can be used to create powerful and effective technology. The processing capability of a quantum computer is triggered by managing quantum particles in a quantum computer, which improves transformation in many domains. Quantum logic operations have the significant benefit of being reversible. Unlike classical irreversible processing, quantum logic gates are reversible and unitary, allowing input bits to be recovered via a one-to-one connection between input and output bits. In QCADesigner, as well as in the Quantum environment, different reversible logic gates may be constructed. Some other promising features include Superposition (Quantum Parallelism), Entanglement, etc. This study uses IBM quantum to create the QCA-based Majority voter gate.
Using cryptography correctly is crucial in the current situation to safeguard data and ensure data security during data transfer. In this digital era, messages must be appropriately encrypted and decoded to prevent data misuse and ensure its accessibility to the intended recipient. Conventional cryptography techniques mostly depend on the mathematical intricacy of the encoding functions and the shared key. One such encoding approach that we may take into consideration is the Vigenere cipher algorithm. In this study, we want to apply this strategy utilizing reversible logic with the assistance of two helpful tools, namely, IBM Quantum (IBMQ) and QCADesigner. The encoder and decoder circuits for the Vigenere cipher are therefore proposed in this work in QCADesigner by utilizing Peres and DG gates in quantum-dot cellular automata (QCA) that consist of a single layer with 42 cells for encryption and 47 cells for decryption. The proposed circuit outperforms the existing ones concerning area, cell count and latency. Given that the layouts’ energy consumption is assessed, it is guaranteed that the QCA nanodevice might serve as a stand-in platform for the creation of reversible circuits. The same simulation outcome was also obtained while building the identical circuits in a quantum presentation using IBMQ. The two applications are closely connected and both rely on quantum concepts. The outcomes are therefore verified for each of the two situations. The reversible Vigenere cipher technique enhances data security. Further sophisticated low-power nanoscale lossless nanocommunication architecture may be created with the help of the suggested circuits.

This study offers a thorough literature survey on high-level security techniques in quantum security for PQC, analysing past and current research efforts in this domain. We first examine the vulnerabilities of classical cryptographic protocols, including public-key encryption methods such as RSA (developed by Rivest, Shamir, and Adleman) and ECC (which uses elliptic curve mathematics), and traditional cryptographic hashing methods, against quantum adversaries. The study then explores the foundational approaches to quantum-secure cryptography, including lattice-based, hash-based, multivariate polynomial, code-based, and isogeny-based encryption methods that possess emerged as promising candidates for standardization. The survey highlights key challenges in the real-world application of PQC, including performance trade-offs, key size overhead, and deployment complexities. We conclude by identifying future research directions during the creation of scalable, efficient, and provably secure cryptographic methods designed to withstand quantum attacks techniques. As the shift toward the quantum-resilient era approaches, this survey aims to provide a clear and structured comprehension of the evolving the domain of quantum security for PQC.
