Deterministic transfer of multiqubit GHZ entangled states and quantum secret sharing between different cavities

Xiao-Ling He, Chui-Ping Yang

We propose a way for transferring Greenberger-Horne-Zeilinger (GHZ) entangled states from $n$ qubits in one cavity onto another $n$ qubits in the other cavity. It is shown that $n$…
