    Abstract

    A quantum information splitting scheme of two-qubit state is proposed by using two asymmetric W states as quantum channel. It’s showed that if the two-qubit state is known to the sender (Alice), then she can split quantum information and distribute it to the receivers (Bob and Charlie) by performing a two-qubit projective measurement. Bob and Charlie first perform a collective unitary operation on their qubits, and then Charlie can recover the initial quantum state by implementing two single-qubit unitary operations. So the scheme reduces greatly the measurement complexity. The success probability and classical communication cost are calculated within the scheme.
