“…In 2001 Mair team [28] was the first to report the realization of entanglement using the OAM of photons by adopting SPDC. The entangled states of two-photon OAM can be experimentally used for QKD protocol [21], [22]. However, the programs can only be encoded and modulated at low dimension because they are entangled states of single degree of freedom photon pairs.…”

The development of intelligent Internet of vehicles (IoV) is based on communication technology, especially the quantum communication of hybrid entangled states based on orbital angular momentum (OAM). The quantum key distribution (QKD) method is demonstrated using hybrid entangled states with multi-degree of freedom and high purity based on OAM. First, the polarization entangled photon pairs are produced by two type I BBO crystals by means of spontaneous parametric down-conversion (SPDC). The polarization-OAM hybrid entangled states are created by q-plate (QP) to realize QKD. It is found that the polarization entangled photon pairs have the characteristics of OAM. A single mode fiber (SMF) is proposed to filter the topological charge non-zero photons and purify the polarization entangled photon pairs. Then the purification setup with M-Z interferometer and beam rotator (BR) is presented which can purify the polarization-OAM hybrid entangled states. The high purity polarization-OAM hybrid entangled states are implemented, and the QP conversion rate of 3 secondary feedbacks is 99.84% theoretically. Analysis indicates that precise purity polarization-OAM hybrid entangled state can increase the fidelity of information and improve the anti-interference ability in this program without mutually unbiased bases (MUBs). The photon utilization rate, energy-efficient and low-latency communication can be greatly improved by using the OAM carrying information. INDEX TERMS Internet of vehicles (IoV), low-latency, orbital angular momentum (OAM), high purity, hybrid entanglement, coincidence measurement.

Abstract.A new QKD implementation scheme of BB84 protocol is introduced based on FPGA. Firstly, the overall design method and the functional division are described in detail. Then, the logic design of the sub-module are significantly studied, including random data module, laser source drive module, error correcting module, receiver/transmitter interface module, extracting original key module and error rate estimation module. Finally, the partial simulation results are given to verify the correctness of the design function. The set-up advantage is the small size, high bitrates, flexible configuration, and convenient algorithm update.
