Abstract
We construct a new kind of four-mode charge-related entangled state |q,k;n,m>θϕ in Fock space, which can describe the process of photons, emitted from two energy levels in a optical cavity, being absorbed by another two levels simultanuously. The relation between |q,k;n,m>θϕ and the four-mode entangled state |η,σ,τ>θϕ (H.-Y. Fan et al., Mod. Phys. Lett.B16, 861 (2002)) is pointed out.
