Abstract: | We demonstrate that a four-qubit cluster state can be used to realize the deterministic quantum state sharing (QSTS) of an
arbitrary four-qubit GHZ-type state among three parties by introducing three ancillary qubits and performing three controlled-NOT
operations. In our scheme, any one of the two agents has the ability to reconstruct the original state if he/she collaborates
with the other one, whilst individual agent obtains no information. |
