Measurement-device-independent quantum secure direct communication based on decoy states and polarization–spatial hyperentanglement
An MDI-QSDC protocol based on active three-intensity decoy states and polarization–spatial hyperentanglement is proposed, which exhibits a higher secrecy rate lower bound than three reconstructed decoy-state QSDC references in the low-loss regime.
