报告摘要：Combining the ideas of quantum state sharing and multi-party quantum remote control, a novel four-participant quantum rotation operation sharing protocol was proposed, which utilizes pre-shared entanglement and local operations. Concretely, using 4-qubit entangle[1]ment of Greenberger-Home-Zeilinger (GHZ) type state as quantum channel, the two senders of the protocol can remotely and independently implement various rotation operations on the target state of any site, which requires mutual cooperation between two agents. More[1]over, by utilizing (M+N)-qubit GHZ type state as the entanglement channel, the above four-participant situation can be easily generalized to the scenario with M senders and N agents.
