Abstract :
We develop an innovative and efficient scheme to share an arbitrary multi-qubit state between n agents via only one GHZ channel under control of m agents in a network. Compared with existing ones in this literature, our scheme involves less qubits, only single-qubit measurements, Bell-basis measurement and CNOT gate operations and thus exhibits a higher overall efficiency.
