Four-component quantum teleportation network system and construction method thereof

The invention discloses a four-component quantum teleportation network system and a construction method thereof, and belongs to the technical field of quantum communication devices among multiple continuous variable users. The technical problem to be solved is to provide an improvement of a four-component quantum teleportation network system structure. According to the technical scheme, the quantum stealth transfer network comprises a continuous variable four-component quantum resource generation device and four spatially separated quantum nodes, and the four quantum nodes are respectively setas a sending node, a receiving node and a control node in the quantum stealth transfer network. The four quantum nodes are used for participating in a transmission process of one quantum state or participating in a transmission process of two quantum states, and the four quantum nodes are all connected with a generation device of continuous variable four-component quantum resources; the four-component quantum teleportati
