Entangled W state can be applied to quantum information processing in the quantum entanglement,and presented a scheme generation of entangled W state via entangled GHZ state in the single mode cavity field.Three two-level atoms(1,2,3) initially in the W entanglement state,then two atoms 2 and 3 are injected into single mode cavity field to make interaction,while atom 1 is far from the cavity field.The result shows that entangled W state can be generated by manipulating the interactions between cavity field and two atoms in appropriate coupling coefficients when atom 1 is be detected.
