Abstract:
One of the problems that we are deal with in quantum information is secure transition of information. In Quantum State Sharing, we can encode our data on the quantum state and share the quantum state among some people such that none of the can be able to retrieve the state without collaboration with others. In this thesis, we will be concerned with reviewing of classical and quantum secret sharing and finally introduce another method in order to share a two qubit secret between N parties such any of the members can retrieve the state only with collaboration with other parties. It will be shown that using only Bell Pairs as recourse and measurement basis makes this model more efficient than the previous one
