Накратко на български

Квантовите алгоритми се използват за симулиране на поведението на кварки и глюони при високоенергийни сблъсъци, като например тези в Големия адронен колайдер. Това помага за по-доброто разбиране на структурата на протони и пиони, както и на ранната Вселена.

Quantum simulation of Jet Evolution and Parton Structure

The Q-JEPS project addresses one of the grand challenges in particle physics: simulating the behavior of strongly interacting particles, such as quarks and gluons, in extreme environments like those created in high-energy collisions at the Large Hadron Collider (LHC) or future Electron-Ion Collider (EIC). These interactions are governed by quantum chromodynamics (QCD), but solving QCD in real-time and in dense media remains one of the hardest problems in theoretical physics. At the same time, quantum computing is rapidly emerging as a transformative technology for solving certain classes of problems beyond the capabilities of classical computers. Q-JEPS brings these two worlds together. It pioneers the application of quantum algorithms to simulate jet evolution — cascades of particles resulting from high-energy collisions — and the internal structure of hadrons like protons and pions. The project’s goal was to discover or build an efficient quantum simulation framework that can model multi-parton jets, their interactions with a dense medium, and compute key observables such as momentum broadening, gluon radiation, entropy growth, and also find a path to compute nonperturbative quantities like parton distribution functions (PDFs) from first-principle. By doing so, Q-JEPS aims to lay the groundwork for a new generation of quantum simulations for fundamental physics, with long-term impacts on how we interpret data from particle accelerators and understand the early universe.

Цел на проекта

Quantum computing has emerged as a new method to simulate many-body quantum systems, especially in nuclear and high energy physics. The goal of this proposal is to develop the first quantum computing framework for multi-particle jet evolution using the light-front Hamiltonian approach and parton structure functions related to core high energy experiments using available noisy intermediate-scale quantum (NISQ) computers. The fruition of this 24-month project will provide an alternative “quantum” perspective to jet physics, which complements current classical models. By using qubit, a two-level quantum state, quantum simulation triumphs over its classical counterpart by taking asymptotically fewer computational resources, especially when quantum processors become available in the next few years. To this end, I propose to spend the first 16 months at my main host, the Galician Institute of High Energy Physics (IGFAE) of the University of Santiago de Compostela (USC), under supervisor Professor Carlos Salgado on jet physics and quantum simulations. Here, I will develop an efficient Hamiltonian and state encoding scheme for the quantum simulation of composite jets in a dense background field to extract useful observables such as the jet quenching parameter. In the next 4 months, I will work at the second host, the University of California Los Angeles (UCLA), with supervisor Professor Zhongbo Kang on parton structure functions. I will study different quantum algorithms, especially quantum imaginary time evolution, to obtain various parton structure functions with quantum computing. In the final 4 months, I will return to USC to build and publish the first open-source quantum simulation software in high energy physics for jet evolution and parton structure calculations. My project will answer some of the most challenging research questions in jet phenomenologies and quantum simulation algorithms, and lay the groundwork for future quantum applications.
