Abstract

We propose a protocol for transferring photons of unknown states to a distant location using path-polarization hybrid entanglement. Our protocol uses a polarizing beam splitter (PBS), a beam splitter (BS), a CNOT-operation, four unitary operations and polarizing detectors. In our protocol, the hybrid entangled states are generated by the PBS, and it is transmitted through the quantum channel containing the BS and CNOT-gate. The measurement results of the polarizing detectors and classical communications determine which unitary operation will be used in the last step for recovering initial states. The security of the channel in transmitting unknown photons between two parties is confirmed by the results of the measurement of each target photon in the control mode.
