  We report the first experimental realization of perfect W-state in a
superconducting qubit based system. In contrast to maximally entangled state,
the perfect W state is different in weights and phases of the terms contained
in the maximally entangled W-state. The prefect W state finds important
applications in quantum information processing tasks such as perfect
teleportation, superdense coding, secret sharing etc. The efficiency of
generation is quantified by fidelity which is calculated by performing full
quantum state tomography. To verify the presence of genuine nonlocality in the
generated state, we experimentally perform Mermin's inequality tests. Further,
we have also demonstrated splitting and sharing of quantum information using
the experimentally generated state.
