Semi-quantum secret sharings (SQSSs), as they are of now, require all the agents choose to measure the received qubits to produce the shared secret key. As a result, to share an n-bit secret key in an (m + 1)-party SQSS, the number of quanta required to transmit is n × 2m, which increases exponentially with the number of agents (i.e. m). This study proposes a new idea on the construction of the secret key for the existing SQSS such that only 2nm qubits are required to produce an n-bit secret key in the (m + 1)-party SQSS.
