We numerically study the dynamics of quantum entanglement generation between remote electron-phonon systems by photoirradiation employing a model of multiple spins and boson modes. The Schmidt decomposition on the time-dependent wavefunction enables us to discuss the mechanism of the entanglement generation as dynamical behaviors of the singular vectors. The calculated results show that an effective entanglement source will be provided by an appropriate measurement on the phonon state.
