Query: Multi-party Semi-quantum Secret Sharing Protocol based on Measure-flip
  and Reflect Operations   The idea of semi-quantum provides a theoretical solution for the shortage of
quantum resources and the high cost of quantum devices. This paper proposes a
multi-party semi-quantum secret sharing protocol, where the quantum party can
share specific messages with the classical parties, and the shared messages can
only be recovered by the classical parties working together. By utilizing the
$(n+1)$-qubit GHZ states and the operations of measure-flip and reflect, the
proposed protocol can use the measured and reflected qubits as the secret keys
instead of only the measured qubits in the previous MSQSS protocols. This
provides an idea to improve the qubit efficiency when extending semi quantum
protocol to the multi-party case. Compared with similar studies, the proposed
protocol has merits in quantum resources, qubit efficiency, and shared messages
types. Finally, our protocol can withstand most typical external and internal
attacks after security analysis.
