Quantum state sharing of an arbitrary three-qubit state by using four sets of W-class states

► A new application of W-class state is investigated for QSTS of a three-qubit state. ► We show that four sets of W-class states can realize the deterministic QSTS scheme. ► Our scheme only needs three-qubit project measurements and local unitary operations. ► Our scheme is showed to be secure against certain eavesdropping attacks.
