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.

Abstract

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.

Abstract

The background of this research focuses on the importance of quantum communication in overcoming the challenges of global communication security and efficiency. Using quantum information theory, this study aims to explore the potential of network quantum communication in presenting safer and more efficient solutions. The research methods used combine hands-on experiments and analysis of quantum theory to understand how quantum communication systems can be applied in the real world. The results show that although there are still technical challenges, especially in qubit management and error correction, significant progress has been made in experiments that integrate quantum communication with satellites and optical fibers. These results open up great opportunities for the development of quantum communication technology in practical applications, especially for cryptography and secure transmission of information. The conclusion of this study highlights that despite the many challenges to be faced, this research makes an important contribution in understanding ways to develop and implement stable and efficient network quantum communication. Further research is needed to overcome technical limitations and accelerate the development of this technology on a global scale.

Abstract

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.

Abstract

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.

Abstract

The background of this research is driven by the rapid development of quantum computing which has the potential to change the paradigm in complexity theory and computational algorithms. The purpose of this study is to explore the advantages and limitations of quantum algorithms in solving problems with high complexity, as well as to understand their role in complexity theory. The research method used involves quantum computer simulations to analyze the performance of Shor and Grover's algorithms in solving cryptographic problems and large database searches, as well as comparing them with classical algorithms. The results show that quantum algorithms have significant advantages in solving certain problems, although there are technical obstacles in quantum hardware that affect overall performance. Quantum computing has great potential in the fields of cryptography and big data processing, but challenges such as quantum errors and decoherence still have to be overcome. The conclusion of this study confirms the importance of further research in improving quantum hardware and developing more efficient algorithms, as well as opening up new opportunities for the application of quantum computing in various industries.
