Quantum key distribution with error rejecting protocol: optical setup and security analysis

High Capacity Quantum Key Distribution Based on Single-Photon in Polarization and Spatial-Mode Degrees of Freedom Against Collective Noise

“…And the self-error-rejecting photonic qubit transmission in both of the polarization and spatial states over collective noise channels has been reported with the success probability of obtaining uncorrupted states of 1/4 using post-selection [31]. These advantages of error rejection were very useful in QKD to improve the security [32,33].…”
