This　paper　shows　that,　based　on　the　single-photon　JC　model　depicting　the　resonant　interaction　of　a　two-level　atom　with　a　single　cavity　mode,　an　unknown　atomic　state　and　cavity　photon　superposition　state　can　be　faithfully　teleported　with　only　a　single　measurement.　The　scheme　is　probabilistic.　its　success　lies　on　the　event　that　the　sender　atom　(or　the　medi-atom,　for　teleportation　of　cavity　field　state)　is　detected　in　the　higher　state.　The　scheme　is　in　contrast　to　the　previous　ones　of　using　a　maximally　two-particle　entangled　state　as　quantum　channel.
