| Abstract: | We present a new scheme for investigating the usefulness of non-maximally entangled states for multi-party quantum state sharing
in a simple and elegant manner. In our scheme, the sender, Alice shares n various probabilistic channels composed of non-maximally entangled states with n agents in a network. Our protocol involves only Bell-basis measurements, single qubit measurements, and a two-qubit unitary
transformation operated by free optional agents. Our scheme is a more convenient realization because no other multipartite
joint measurements are needed. Furthermore, in our scheme various probabilistic channels lessen the requirement for quantum
channels, which makes it more practical for physical implementation. |
