| Popis: | We propose schemes for quantum information splitting by using asymmetric multi-particle entangled state. Explicit protocols for the quantum information splitting of a single-qubit state and a two-qubit entangled state via asymmetric three-particle entangled state are illustrated. The four-particle asymmetric entangled state are also used as quantum channel to split the unknown two-qubit entangled state. We also consider the security against certain eavesdropping attacks. |
