摘要：

Non-Gaussian states play a crucial role in continuous-variable quantum information. However, there are few reports on multipartite non-Gaussian entanglement. Here, the genuine tripartite non-Gaussian entanglement produced by triple-photon parametric down-conversion in an optical cavity is investigated. Triple-photon parametric down-conversion is a third-order nonlinear process which is different from the two-photon parametric down-conversion process. A three-dimensional optical superlattice can achieve three-dimensional phase-matching for the three-photon parametric down-conversion process. A cavity is included in the triple- photon down-conversion to enhance the nonlinear conversion efficiency. By utilizing the criterion for genuine tripartite non-Gaussian entanglement, it is demonstrated that the capability to control non-Gaussian entanglement properties by adjusting the parameters of the nonlinear process within a wide range. The genuine non-Gaussian entanglement can also be generated after injection a signal. The results are helpful to understand quantum correlations among optical fields generated by three-photon parametric down-conversion and have potential applications in quantum information processing.
