Abstract
This paper proposes a scalable three-level hierarchical quantum information splitting (HQIS) protocol with double quantum unknown states. Generally, the traditional HQIS is to distribute the secret to two levels of receivers for purpose of achieving the secret recovery with the help of some receivers to recover the secret. Our proposed protocol uses the product states of two four-particle cluster states and two three-particle GHZ state as quantum channels to transmit the information of double-quantum unknown states, which can face more complex application scenarios and realize the extension of the agent level. By using multi-qubit GHZ state, the proposed protocol can be modified and extended to achieve the change of the number of agents, and it can make the scheme scalable. Finally, we analyzed the efficiency and safety of the scheme and gave a comparison of its similar schemes.
