A generalized tripartite scheme for splitting an arbitrary 2-qubit state with three 2-qubit partially entangled states and the Kraus measurement

We put forward a generalized tripartite scheme for splitting an arbitrary 2-qubit pure state with three 2-qubit non-maximally entangled states as quantum channels. The scheme for the first time incorporates the Kraus measurement into quantum information splitting scheme. In contrast to the similar scheme using the same quantum channels and the ancillaentangled measurement, our scheme is superior in terms of operation and complexity, success probability, resource consumption and efficiency.
