Abstract: | In this paper, we present a multi-partner communication network
protocol. The supervisor prepares numerous Einstein--Podolsky--Rosen
(EPR) pairs and auxiliary qubits. He then performs a
controlled-NOT(CNOT) gate operation on one qubit of each EPR pair
and an auxiliary, which induces the entanglement between the EPR
pair and the auxiliary. The supervisor keeps one qubit sequence in
his laboratory and sends the others to the outside world. After
security approval, the network can be constructed successfully,
which can be applied to quantum secret sharing and quantum secure
direct communication. |
