The project progressed through four key scientific work packages:
Multi-jet simulation on quantum devices: Using the light-front Hamiltonian formalism, Q-JEPS constructed and simulated three-particle quark-gluon Fock states on quantum circuits, going beyond the two-particle targets originally planned. The simulations, performed using IBM Qiskit and high-performance tensor network backends, revealed how jet energy loss and gluon production emerge in dense QCD matter. This work resulted in two peer-reviewed publications in Physical Review D. An extension to heavy quark simulation framework was also published in Physical Review D.
Modeling a dynamic thermal medium: A novel approach was developed to encode a quantum medium using unitary operators and variational circuits. This work resulted in two peer-reviewed publications in Journal of High Energy Physics. They also enabled the simulation of real-time thermalization (ongoing).
Simulating hadron structure with quantum algorithms: During a secondment at UCLA, I implemented quantum imaginary time evolution and tensor network methods to extract PDFs in the Nambu–Jona-Lasinio model. This marked a step toward practical quantum simulations of partonic structure in nucleons and the paper is currently under review. This collaboration also sparkled two additional projects that are currently ongoing (scattering of mesons in first principle and computing hadronic tensor)
Software framework (ongoing): A modular open-source toolkit has been developed to enable researchers to simulate jets, construct Hamiltonians, evolve quantum states, and extract observables. The code and supporting documentation will be released via GitHub and arXiv at project completion.
Q-JEPS has produced 7 peer-reviewed publications in total (excluding conference proceedings), with additional manuscripts in preparation, and received widespread attention through conference presentations, workshops, and international collaborations.
