- Large quantum photonic systems hold promise for surpassing classical computational limits, yet their state preparation remains a challenge. We propose an alternative approach to study multiparticle dynamics by mapping the excitation mode of these systems to physical properties of the Laguerre¿Gauss modes. We construct coherent states establishing a direct link between excitation number dynamics and the evolution of the Laguerre¿Gauss modes. This highlights the photon transverse spatial degree of freedom as a versatile platform for testing the fundamental aspects of quantum multiparticle systems. © 2024 Optica Publishing Group.
