We show that the electron density matrix evolves as an average over trajectories $\\{\\rho_\\alpha\\}$ weighted by the Sudarshan--Glauber $P$ distribution $P(\\alpha)$ in the weak light--matter coupling regime. Each trajectory obeys an equation of motion, $\\mathrm{i} \\partial_t\\rho_\\alpha=\\mathcal{H}_{\\alpha} \\rho_\\alpha-\\rho_\\alpha\\mathcal{H}_{\\alpha}$, where an effective Hamiltonian $\\mathcal{H}_{\\alpha}$ becomes non-Hermitian due to quantum interference of light.
