Накратко на български

Квантовите свойства на частиците при сблъсъци в Големия адронен колайдер се анализират чрез инструменти от квантовата информатика, като например квантовото заплитане. Това помага за по-доброто разбиране на тъмната материя и разликата между материята и антиматерията.

Exploring quantum observables at the LHC

Our world is made of fundamental particles that interact through a small set of basic forces. Understanding how these particles behave is essential for uncovering the deeper structure of the universe. The Large Hadron Collider (LHC) at CERN collides protons at unprecedented energies, offering a unique opportunity to test the limits of our understanding of physics. As experimental precision increases, however, new ideas and methods are needed to extract as much information as possible from the data. This project addressed that challenge by introducing a new way of analysing particle collisions: applying concepts and tools from quantum information science to high-energy physics. Quantum information is the field that studies how quantum systems store and process information, forming the basis of technologies such as quantum computing. Despite the fact that particles produced at the LHC are inherently quantum objects, these techniques had rarely been used to study them. The main objective of the project was to explore whether quantum-information-inspired observables—such as quantum entanglement—can be measured directly using the particles produced in LHC collisions. In this framework, the particles produced in a collision are treated as physical realisations of qubits, the fundamental units of quantum information. By building this innovative bridge between two previously separate research areas, the project aimed to open a new window on the subatomic world and propose fresh directions for addressing some of the biggest open questions in particle physics, such as the nature of dark matter and the origin of the asymmetry between matter and antimatter.

Цел на проекта

The main motivation driving the research in collider particle physics is the possibility to address some of the mysteries in the fundamental inner workings of our Universe and to answer to questions left open by the Standard Model of particle physics (SM).Despite the unprecedented energy reached and the large amount of data collected at the Large Hadron Collider (LHC) no convincing evidence of physics beyond the SM has been found. The start of the third LHC data-taking phase (2022) call for novel and unconventional approaches to search for new phenomena, looking in directions yet to be explored. This project proposes to exploit quantum effects, and in particular entanglement among particles as a new observable to probe interactions at high scales. By leveraging on quantum information concepts and techniques, I will explore new experimental strategies to analyse collider final states searching for SM extensions, through unexpected modifications of quantum correlations. The sensitivity of quantum correlations to new physics effects will be investigated both through a model independent effective approach as well as through specific models encompassing new resonances.This proposal aims to provide a first complete guidance and therefore to open the way to LHC experiments on how to perform and interpret measurements of quantum observables in the WW and top pair final states, at low as well at high energy, with specific techniques optimised for each kinematical region. Its ambition lies not only in the scope but also in development of new experimental technique based on charm tagging that has the potential to enlarge the data sample and therefore significantly extend the reach of the new physics searches.
