Quantum stealth state transfer system based on SAM-path-OAM mixed W state

The utility model discloses a quantum stealth state transfer system based on an SAM-Path-OAM mixed W state. The system comprises an Alice sending end and a Bob receiving end, Alice comprises a hybridentanglement unit, an entanglement exchange unit, a Path analysis unit and an SAM analysis unit, and Bob comprises an OAM analysis unit. The entanglement exchange unit is used for carrying out entanglement exchange on the SAM-OAM entanglement photon pair, the SAM-Path entanglement photon pair and the SAM-SAM entanglement photon pair to obtain two W states which are equal in probability and symmetrical to each other, and randomly selecting one W state as a quantum channel; the OAM analysis unit is used for OAM analysis, and Alice can utilize electric field tuning to remotely control OAM generation of Bob photons. The quantum teleportation system is in an open type invisible teleportation mode, can form an asymmetric light quantum network, can realize remote control, high dimension, capacityexpansion and safer quant
