AbstractSARS‐CoV‐2 epidemic (severe acute respiratory corona virus 2 syndromes) has caused major impacts on a global scale. Several countries, including India, Europe, U.S.A., introduced a full state/nation lockdown to minimise the disease transmission through human interaction after the virus entered the population and to minimise the loss of human life. Millions of people have gone unemployed due to lockdown implementation, resulting in business and industry closure and leading to a national economic slowdown. Therefore, preventing the spread of the COVID‐19 virus in the world while also preserving the global economy is an essential problem requiring an effective and immediate solution. Using the compartmental epidemiology S, E, I, R or D (Susceptible, Exposed, Infectious, Recovery or Death) model extended to multiple population regions, the authors predict the evolution of the SARS‐CoV‐2 disease and construct an optimally scheduled lockdown calendar to execute lockdown over phases, using the well‐known Knapsack problem. A comparative analysis of both classical and quantum models shows that our model decreases SARS‐CoV‐2 active cases while retaining the average global economic factor, Gross Domestic Product, in contrast to the scenario with no lockdown.

It has always been difficult to make an exact prediction when there are many missing numbers in the data collection. To solve this problem, the majority of hybrid models either removed the absent cases from the data collection or used a default method to fill in the blanks. In the study described in this article, an improved genetic algorithm metaheuristics-based forecasting model is suggested to forecast the number of confirmed instances of hepatitis. The Random Forest's characteristics are chosen using the improved genetic method, which also improves the efficiency and accuracy of the prediction model overall. On standard medical data sets for Hepatitis from the UCI Repository of Machine Learning, the effectiveness of the suggested model as a predictive categorization system is examined. In addition to accuracy, sensitivity, specificity; and the area under ROC are also computed. The proposed method was contrasted with various current state-of-the-art approaches that were examined in the same setting and using the same datasets. Based on the outcomes of the simulations and the comparative analysis that was done, it was found that the suggested hybrid method outperformed more complex ones with an accuracy of 93.91% and that it could be applied to other prediction models.

Quantum-dot cellular automata (QCA) technology leads to rapid high-density combinatory low power exploitation to realize the reversible logic circuit in the nanoscale era. Reversible logic is an alternative to overcome excess energy indulgence of irreversible process. This paper illustrates a cost-effective, energy-efficient Universal Reversible Logic Gate in QCA framework which is capable of designing power analysis attack resistable hardware cryptographical circuit. The proposed (URLGs: U1 and U2) has been tested with simulator QCADesigner V2.0.3, outshined the existing pattern relating to the area, gate count, garbage count, and quantum cost. We found 37.5% garbage minimization is achieved compared to NFT, which is utmost minimization of garbage ever reported in QCA literature. Thirteen three variable standard Boolean functions are considered as logic benchmarks to guesstimate the capability and efficiency of proposed URLG in QCA circuit implementation and synthesizing logic gates. In average, our proposed U2 achieved 36.66% improvement in energy dissipation for different kink energy ratios over early reported work.

Aims: Embedded system plays a vital role in today’s life. Hence, our interest is in areadelay- energy efficient embedded system design in post-CMOS technology, i.e., QCA. Objectives: The research is focused on efficient area-delay-energy Configurable Logic Block (CLB) design for Field-Programmable Gate Array architecture (FPGA) with successful simulation-based on next-generation technology, Quantum-dot cellular automata. Methods: Each proposed circuit is designed on post CMOS 4 dot 2 electron technology, i.e. QCA (Quantum dot Cellular Automata), is adopted in circuit implementation due to low power dissipation, high clock frequency and high package density. QCADesigner is used to verify the functionality of every circuit. QCAPro tool is used for determining power dissipation. Results: In contrast, a new approach of using de-multiplexer replacing the decoder has been introduced that results in the reduction of the average energy dissipation by almost 57%. A NOR based D flip-flop memory architecture and multiplexer are also used in the lookup table for the configurable logic block. The proposed architecture thus reduces the overall latency. The proposed CLB consists of 6356 QCA cells covering 7.44 um2 area. Write and read latency of proposed CLB are 12 and 7.25 QCA clock, respectively. Conclusion: The present paper concludes that read and write latency reduction occurs; average energy dissipation, leakage, and switching energy dissipation are reduced in a large amount resulting in an advantage of the overall minimization of the latency for the proposed CLB in the process.

Tile Nanostructures in Quantum-dot Cellular Automata (QCA) are proved to be a robust and reliable structure to fabricate the logic device. In this scientific attempt, we have focused on N-variable symmetric Logic function synthesis in Quantum-dot Cellular Automata with tile nanostructure. Coupled Majority-minority voter (CMmV) voter is applied to implement 2 –variable and 3 –variable logic syntheses in Quantum-dot Cellular Automata. The N-variable symmetric logic function is applicable to implement any logic circuit. Two and three variables Quantum-dot Cellular Automata symmetric logic functions are synthesized in this article. Hence any digital logic circuit can be implemented with proposed Coupled Majority-minority voter (CMmV).

The information are need to modulate using irreproducible and unpredictable digital bit stream to get a secure digital communication systems. Hence, True random number generator (TRNG) is a significant aspirant in digital circuit to yield unpredictable digital bit stream. In this assignment self starved feedback SRAM based TRNG is proposed in quantum cellular automata (QCA) technology. Moreover, QCA technology is adopted to design TRNG components due to its features like ultra low power dissipation, low area and ultra high operating frequency. The proposed TRNG is comprised of self starved feedback circuit and floating clock generator. Again, the basis of self starved feedback circuit is a single bit QCA SRAM cell, which extracts the random digital bit. Furthermore, to enhance the randomness, floating clock generator is implemented across self starved feedback circuits input. The functionality of proposed TRNG is accomplished through QCA Designer tool and its architecture is also passed NIST statistical test of randomness. Hence proposed 8 bit TRNG can be interpreted as a novel contender for security applications due to its 14.82 GHz operating frequency, 0.36 μm 2 area, latency of 1 QCA clock cycle, 28.53 meV average power dissipation and high tail probability of NIST test battery report in QCA technology.

True random number generator, commonly known as TRNG, is an important candidate in today’s cryptography process. TRNG is only innovative design which can generate non-deterministic and unique digital bit stream to any communication systems or secured system. Quantum cellular automata (QCA) technology is adopted to design TRNG due to its low area, ultra high operating frequency, and low power dissipation. This article presents a QCA majority voter-based TRNG, which is comprised of crossed loop circuit and seed circuit. The random bits are extracted from crossed loop circuit which is composed of “OR” gate. Again the seed circuits are used here to enhance the unpredictability of generated number sequence and quality of random number. The proposed TRNG design is verified through QCADesigner tool 2.0.3, and its architecture is passed industry standard successfully. In area, latency, and energy point of view, the proposed 8-bit TRNG is consumed 0.36 um2 area, 1 QCA clock cycle latency, and 49.7 mev energy (per bit). So, proposed TRNG will be interpreted as a promising design in next-generation cryptography domain.

Ternary quantum dot cellular automata (tQCA) is an emerging as well as an interesting field of research area after successful fabrication of binary QCA. Ternary logic is a critical choice for solving greater data storage, faster arithmetic operation on complex data, and so on. In this paper, tQCA basic logic gates like ternary AND, OR, NOT gates and buffers have been reported. tQCA layout for basic logic gates is simulated with tQCA simulation software (TQCA_1.7.0.2). Involvement of coulombic interactive force is also explored as physical proof of NOT gate operation in eight-dot tQCA device model.

In this paper, an attempt is made to present a method of quantum cost minimization or optimization technique for quantum reversible circuits using proposed merger rules in Exclusive Sum of Product (ESOP) method. These modified ESOP methods are used to minimize the quantum circuits. We found that the quantum cost is drastically decreased than the previous ESOP method. It will be easy to find the quantum cost and quantum gate optimized quantum circuits implementation. It will also reduce quantum error while the quantum circuit is executed in real quantum processor.

Information processing and conventional computing are usually resource constrained; evermore they need to operate in a physically suspicious environment. Consequently, communication architectures, protocol and its security aspects have been the focus of many recent research works. Our proposal demonstrates how to amend this vulnerable circumstance through a three-stage security scheme in quantum-dot cellular automata (QCA) based nano-architecture. The primary objective of this hardware-based cryptographic architecture using QCA is to intend a distinctly secure communication architecture comprising less number of QCA cells, which enchant the comparative performance investigation along with the power-area constraints. In our proposed design the random bits are extorted from an asymmetrically arranged crossed loop TRNG where the seed circuits are used to boost the volatility of initiated number sequences as well as the distinction of the random numbers. In this work, a novel encryption-decryption prototype for a secure communication system has been implemented. The simulation results are obtained from QCADesigner tool v2.0.3, which fruitfully agreed with the industry standard. An intact evaluation of the proposed TRNG and the comparative analysis with a recent work of TRNG has been authorized by the 7.79% improvements in average energy dissipation for different Kink energy ratio. Altogether the proposed architecture and its contemporary implementation in QCA framework can be recognized by means of the advantages in 7.02% circuit complexity, 11.53% area, and 13.77% average leakage power dissipation with respect to the recent work of TRNG. Thus our proposed novel TRNG based hardware cryptographic architecture can be considered as a potential next-generation network-on-chip (NoC) realization for a large-scale cryptosystem in QCA technology.
