Journal of Tecnologia Quantica
Journal of Tecnologia Quantica is dedicated to bringing together the latest and most important results and perspectives from across the emerging field of quantum science and technology. Journal of Tecnologia Quantica is a highly selective journal; submissions must be both essential reading for a particular sub-field and of interest to the broader quantum science and technology community with the expectation for lasting scientific and technological impact. We therefore anticipate that only a small proportion of submissions to Journal of Tecnologia Quantica will be selected for publication. We feel that the rapidly growing QST community is looking for a journal with this profile, and one that together we can achieve. Submitted papers must be written in English for initial review stage by editors and further review process by minimum two international reviewers.

<![CDATA[Quantum mechanics presents challenges in understanding probability, which is often seen as a measure of uncertainty in quantum systems. Quantum Bayesianism (QBism) is an alternative interpretation that considers probability as an observer's subjective belief, not as an objective representation of the state of the system. This study aims to delve deeper into the role of probability in quantum mechanics through the perspective of QBism. This study aims to examine the differences between Quantum Bayesianism and traditional quantum probability interpretations, as well as analyze how QBism can provide a more dynamic understanding of probability in quantum experiments. The methods used include literature analysis to identify publication trends related to QBism as well as case studies of quantum experiments that show the application of subjective probability theory. Data is obtained from various scientific sources and the latest publications in the field of quantum physics. The results show that Quantum Bayesianism provides a more flexible and subjective approach to probability, which allows probabilities to be calculated based on the observer's beliefs and can change according to the information obtained. The study also confirms that more and more researchers are adopting QBism in their research, replacing the more traditional view of objective probability. The study concluded that QBism offers a more relevant and applicable view of probability in quantum mechanics. Although there are still limitations in practical application, QBism opens up new opportunities in the understanding and development of quantum technology in the future.]]>

<![CDATA[The background of this research focuses on the security challenges faced by electronic voting (e-voting) systems that are vulnerable to the threat of eavesdropping and data manipulation. As the use of digital technology in elections increases, innovative solutions are needed to ensure the integrity and confidentiality of voters' votes. This study aims to explore the application of Quantum Key Distribution (QKD) in a safe and reliable e-voting system. The method used is a case study of the implementation of QKD in various e-voting trials in several countries, with an analysis of the test results of the success rate, security, and speed of data transmission. The results show that the application of QKD in the e-voting system is able to provide a security level of up to 99%, even with a decrease in data transmission speed compared to conventional systems. The resulting security is much higher, overcoming the potential for eavesdropping and data forgery attacks. The conclusion of this study is that QKD can be an effective solution to improve security in e-voting systems, although transmission speed challenges need to be improved. Further research is needed to optimize this technology so that it can be applied at scale with better efficiency.]]>

<![CDATA[The background of this research focuses on the challenges of monitoring the deeper structure of the Earth, especially related to the variations in magnetic and gravitational fields that indicate geological changes and tectonic activity. Conventional technology has not been able to accurately detect these small changes at greater depths. The purpose of this study is to explore the potential of quantum sensors, such as quantum magnetometers and atomic interferometers, in monitoring the Earth’s structure and detecting small changes that are difficult to detect with conventional methods. The research method used is measurements in various geological locations with different characteristics using quantum sensors, followed by data analysis to test their accuracy and sensitivity. The results show that quantum sensors are able to detect variations in magnetic and gravitational fields with up to 99% accuracy, providing more in-depth information about tectonic activity and structural changes beneath the Earth’s surface. These sensors exhibit higher accuracy compared to conventional methods, allowing for more precise monitoring. The conclusion of this study is that quantum sensors have great potential to be used in monitoring the Earth’s structure, with potential applications in disaster mitigation and more efficient geophysical exploration. Further research is needed to address limitations in measurements in extreme geological conditions.]]>

<![CDATA[Quantum computing offers great potential for a technological revolution, but challenges related to the stability and resilience of computing systems remain a major obstacle. Topological Quantum Computing (TQC) emerged as one of the solutions to overcome this problem. This study aims to analyze the challenges and potential of TQC in the development of quantum computing that is more stable and resistant to external disturbances. The method used in this study is a literature study by analyzing secondary data from various experiments conducted by leading research institutions. The results show that TQC has the potential to improve the reliability of quantum computing, especially in reducing the error rate that often occurs in conventional quantum systems. Nonetheless, the main challenges faced are the greater scalability and integration issues of the system. The study concludes that despite the promise of TQC, the development of this technology still requires further research to overcome existing technical constraints. The future research direction needs to be focused on the development of topological qubits on a large scale and more efficient integration for practical applications.]]>

<![CDATA[The background of this research focuses on the phenomenon of quantum entanglement in multi-particle systems involving photons and atoms. Although much research has been done on entanglement in two-particle systems, challenges arise when the system is expanded to include more particles. This study aims to explore how entanglement is maintained in multi-particle systems and to understand the differences between photons and atoms in this context. The method used is an experiment that involves measuring entanglement in a system of photons and atoms that are separated at a certain distance. The results showed that photons can maintain entanglement over very long distances (up to 1 kilometer), while atoms show a decrease in entanglement levels over longer distances, but can still be used in quantum computing applications at shorter distances. The study concluded that photons are more stable in maintaining entanglement over long distances, while atoms are more suitable for quantum computing applications in small systems. Further research is needed to address the limitations related to the stability of entanglement over longer distances and to develop applications in larger multi-particle systems.]]>

<![CDATA[The second law of thermodynamics is one of the basic principles of physics that applies in the classical and quantum worlds. Although this principle is widely accepted, its application in quantum systems is still the subject of intense research. This research focuses on the application of the second law of thermodynamics in the quantum world, with an emphasis on the influence of quantum entanglement on entropy and energy changes in quantum systems. The purpose of this study is to explore how the second law of thermodynamics applies in quantum systems and how quantum entanglement affects the rate of entropic change. This study aims to identify the differences between quantum systems and classical systems in the context of thermodynamics. This study uses experimental and simulation methods on simple quantum systems, such as trapped ions, to measure changes in entropy as temperature increases. The data obtained were analyzed to identify the influence of quantum entanglement on the rate of entropy change and how this differs from classical systems. The results showed that quantum entanglement affected the rate of entropy increase, with quantum systems showing slower entropy changes compared to classical systems. This suggests that entropy in quantum systems is not only affected by temperature, but also by quantum interactions between particles. This study concludes that the second law of thermodynamics remains valid in the quantum world, but with significant modifications due to the influence of quantum entanglement. These findings pave the way for the development of more complex and applicable quantum thermodynamic models, which can be used in the design of future quantum technologies.]]>

<![CDATA[The background of this research focuses on the confluence of two major theories in physics, namely quantum mechanics and general relativity, which are very important in explaining gravity at the quantum scale and cosmology. The purpose of this study is to investigate the relationship between quantum gravity theory and its implications for cosmological phenomena, especially related to singularities and enormous models of the universe. The method used in this study is a comparative analysis of various existing theories of quantum gravity, including string theory and quantum loop gravity, as well as a literature review on the application of these theories in cosmology. The results show that although various theories have been developed, there is not yet a clear consensus on how to integrate quantum gravity into the broader cosmological model. The study also revealed a huge gap in the experiments that could confirm these theories, which slowed down our understanding of gravity at the quantum scale. The conclusion of this study is the importance of further research in experiments and theories to bring together the principles of quantum and general relativity, which is expected to lead to a new, more comprehensive model of cosmology and the universe.]]>

<![CDATA[Quantum field theory and general relativity are the two main pillars of modern physics. However, the two still cannot be combined consistently to explain cosmic phenomena at the microscopic level, especially in the context of curved spacetime. This research aims to explore the interaction between quantum fields and the curvature of spacetime, with a focus on the implications of quantum gravity. This research aims to understand how quantum fields interact with curved spacetime, as well as to develop a more comprehensive model of physics that combines these two concepts. The methods used include the development of mathematical models and numerical simulations to integrate quantum field theory with general relativity. The analysis was carried out by examining the impact of space-time curvature on quantum field fluctuations around massive objects such as black holes. The findings show that the curvature of spacetime has a major influence on the behavior of the quantum field, leading to modifications in energy distribution and field fluctuations. This discovery opens up new possibilities in the development of a more complete theory of quantum gravity. This study provides new insights into understanding the relationship between quantum fields and curved spacetime, as well as opening the way for further research in the field of quantum gravity and extreme cosmic phenomena. ]]>

<![CDATA[The problem of quantum measurements has become one of the most controversial topics in quantum physics. Various interpretations of the role of observers and measurement processes in the quantum world have been proposed, but there is no clear consensus yet. The study focuses on the various proposed solutions to quantum measurement problems, highlighting the theory of decoherence and Many Worlds as promising alternatives. The purpose of this study is to analyze the various proposed solutions to quantum measurement problems and explore the relevance of decoherence theory and Many Worlds in explaining measurements without directly involving observers. The method used in this study is a literature analysis of 30 leading publications that discuss the topic of quantum measurement problems and proposed solutions. The data collected included theoretical and experimental studies relevant to Copenhagen's interpretation, Many Worlds, and decoherence theory. The study found that Copenhagen's interpretation continues to dominate the literature, but approaches such as Many Worlds and decoherence are gaining more attention. Decoherence theory in particular offers a more adequate explanation for bridging the gap between the quantum world and the classical world without requiring the role of an observer in measurement. The study concludes that although many solutions have been proposed, decoherence theory provides a more cohesive and comprehensive alternative in addressing quantum measurement problems. Further research is needed to test the reliability of these theories in more controlled quantum experiments.]]>
