. Quantum computers take advantage of interfering quantum alternatives in order to handle problems that might be too time consuming with algorithms based on classical logic. Developing quantum computers requires new ways of thinking beyond those in the familiar classical world. To help in this thinking, we give a description of the foundational ideas that hold in all of our successful physical models, including quantum theory. Our emphasis will be on the proper interpretation of our theories, and not just their statements. Our tact will be to build on the concept of information, which lies central to the operation of not just computers, but the Universe. For application to quantum computing, the essence of quantum theory is given, together with special precautions and limitations. Introduction. Having a grasp on the ideas behind a theory helps to apply it correctly, to understand its limitations, and to generate new ideas. Getting a firm hold on quantum theory is not an easy task, because our experiences and even our genetic predispositions have been developed in a world in which quantum effects are largely washed out. Remarkably, our predilection for finding logic behind the behavior of what we observe, including that of electrons and atoms, has led us to quantum theory, a description of nature that is hard for us to conceptualize, but is logical, accurate, and explains a wide variety of phenomena with only a few statements and input. As background to quantum theory and quantum computing, an attempt is made here to give the primitive notions and essential observations that underlie current physical theories, so that foundational ideas are explicit, and a common language is established. In our description, information storage and transfer is made central. A short description of quantum theory follows, and then applied to quantum computing, focusing on what the theory says, and particularly does not say, in areas where conceptual difficulties have arisen. Physical theory and reality. A physical theory is a logical model capable of making predictions of what we observe. It is judged by its accuracy in matching measurements, and by its economy, i.e. whether the proposed theory has only a few relationships and input data needed for its ability to explain observations over a wide realm.
Purpose: This work aims to understand the relevance of nanotechnology in the enhancement of quantum computing with an emphasis on the perceptions of workers in the fields. The research is going to examine the identification of these perception factors thereof by elaborating on the field of expertise of the participants of this research, their experience in the field, and their awareness of quantum bits or qubits to offer future guidelines for pertinent research and development. Objective: The goals of this research are as follows: The first is to evaluate the present status of nanotechnology in quantum computing, second, to define the factors, which influence the professional meaning of the concept, and third, to discover the literature deficiencies. The present research also intends to provide suggestions on how interpersonal and interprofessional cooperation and research in this emerging area can be improved. Methodology: Consequently, there was the use of a cross-sectional survey design, and participants included experts in nanotechnology, quantum computing, and related areas. The questions posed in the survey addressed respondents’ experience, their view on the role of nanotechnology and their background. Data collected in this study were analyzed using the chi-square tests, ANOVA test, T-tests, correlation analysis, and regression analysis to examine the relationship between variables and determine the goodness of fit in the tests. The survey sample included 210 participants and therefore offered considerable reliability for the evaluation. Results: The first sets of chi-square tests revealed no correlation between the field of speciality and views on nanotechnology (χ² = 14. 77, p = 0. 789), or between their level of quip familiarity and preference for nanomaterials (χ² = 13. 56, p = 0. 631). ANOVA test, which compared the perceived significance of nanotechnology to the years of experience, brought out an F-statistic of 0. 96 which is non-significant at p > 0. 05 of 0. 428. The T-test of researchers’ and graduate students’ perception of nanotechnology showed an insignificant value at p > 0. 05 of 1. 17. According more to the correlation analysis the results of the correlation between years of experience and perceptions of nanotechnology were non-significant (r = - 0. 03 p = 0. 664). Years of experience and familiarity with qubits explained less than 1 % of the total explanation of the perceptions (R² = 0. 002, F = 0. 22, p = 0. 803). Practical Implications: Evidently, the current study established that nanotechnology is unanimously considered of extreme importance in quantum computing, to those with no experience in it, or those coming from different fields of specialty. This reflects the need for increased funding of open-ended nanoscale research and development and industries to work together as a system to solve the engineering issues that remain in communication in the development of quantum systems. The outcomes also reflect the importance of maintaining efforts in introducing nanotechnology as a part of educational programs in quantum computing so that the new generation of specialists could contribute to the development of the field. Novelty: Thus, this study is one of the first ones which invests empirical evidence on experts’ perceptions of nanotechnology in quantum computing and involves a large and heterogeneous sample. Therefore, using a wide variety of statistical methods, the research offers a more detailed picture of factors that affect these perceptions and points to what concerns may be relevant for future studies. The results enrich the current discussion on the further evolution of quantum computing and the scientists’ plans for the coming decades integrating nanotechnology into the new field. Conclusion: The findings demonstrate a general appreciation of the significance of nanotechnology in quantum computing across scholars in the field with no variation across the fields of specialization, years of experience, or career development. At the same time, the results suggest the hypothesis that other factors influencing the perceptions remain more important than the investigated ones and are not included in this study. These results compellingly suggest that further technical research is still needed to address the barriers which limit the extension of quantum computing and help define a feasible roadmap for this disruptive technology.
Abstract: Quantum computing is a new type of computing that uses the principles of quantum physics to perform calculations in ways that are not possible with traditional computers. Unlike classical computers, which process information using bits that are either 0 or 1, quantum computers use quantum bits (qubits) that can exist in multiple states at the same time. This ability allows quantum systems to solve certain complex problems much faster than classical machines. This paper presents a simple and human-centered explanation of quantum computing, focusing on how it works, why it matters, and how it can be applied in real-world situations. The study discusses key concepts such as superposition, entanglement, and quantum gates using easy-to-understand language. It also explores practical applications including cryptography, optimization, drug discovery, and material simulation. In addition, this paper examines the current challenges in quantum computing, such as hardware instability, error correction, limited qubit scalability, and high implementation cost. A conceptual hybrid classical–quantum system model is proposed to show how quantum and classical computers can work together to solve complex problems more efficiently. The goal of this research is to make quantum computing more understandable to students, educators, and decision-makers, and to encourage early awareness and responsible development of this powerful technology.
