Hybrid-dimensional quantum correlations

In the exciting realm of quantum information science, researchers are harnessing the principles of quantum mechanics a fundamental theory in physics that explains the behaviour of energy and material on the atomic and subatomic levels to revolutionize how we handle and transfer data. This field is rapidly growing, especially with the increasing need for advanced technology applications. One key area of focus is quantum optics, which has evolved from just studying light and its interaction with matter to becoming a cornerstone in various technological and scientific endeavours. At the heart of this evolution is the photonic platform, which uses light in technological advancements. It`s especially crucial in systems that depend on managing and controlling quantum correlations that are fundamental to quantum technology. These correlations include phenomena like entanglement (a connection between parties, even when separated by large distances), squeezing (a way to reduce uncertainty in measuring certain properties), and non-Gaussianity (a measure of deviation from a standard Gaussian quantum field). This research project aims to tackle some important questions in this field. We`re primarily focused on finding the best ways to identify and measure quantum effects in real-world scenarios that use light as a carrier. This means developing comprehensible and applicable methods that can be observed and controlled in the laboratory. We`re particularly interested in how these correlations behave in complex systems involving multiple parts and varying dimensions of the quantum system. Our approach is to delve deep into the relationship between physics and information. We`re looking at how entanglement works and can be used, exploring new ways to measure it in intricate networks, and studying the nature of light sources in quantum experiments. We aim to find new methods to distinguish between different types of correlations and to better understand how `quantumness` is distributed in various quantum states. What makes our project stand out is its focus on systems that combine multiple parties and dimensions an area that`s ripe with potential for new quantum technologies. These hybrid systems, which blend quantum bits and light fields, are key for transmitting and storing quantum information efficiently. They also act as bridges, combining different forms of quantum technology. Our goal is to develop clear criteria and identify the necessary tools to deepen our understanding of these complex correlations as we study larger and more complex systems. Our project is about unlocking the secrets of quantum correlations in practical, scalable ways.
