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

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.

Abstract

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.

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 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.

Abstract

Research Background: Quantum Biology is a branch of science that studies the interaction between quantum mechanics and biological systems. Some early studies have shown that quantum phenomena affect the efficiency of biological processes, but understanding of their applications is still limited. Research Objectives: This study aims to investigate how quantum mechanics plays a role in biological processes, especially in photosynthesis and magnetic navigation in migratory birds. Research Methods: This research uses laboratory experiments with an interdisciplinary approach, combining quantum physics and molecular biology techniques. The samples used included plant culture cells and migratory birds, as well as data analysis using mathematical modeling to describe quantum phenomena in biological systems. Research Results: The results show that quantum phenomena, such as coherence and entanglement, play a role in improving the efficiency of photosynthesis and the ability of birds to navigate based on the Earth's magnetic field. The study also identified a quantum mechanism that accelerates metabolic processes in cells. Research Conclusions: This study provides strong evidence that quantum mechanics can directly affect biological systems. These findings open up opportunities for the development of quantum-based biotechnology, as well as provide new insights into understanding more efficient and coordinated biological processes.
