    Abstract

    Multiplexed entanglement with high-capacity characteristics serves as an important resource in quantum information processing. Orbital angular momentum (OAM) multiplexing, which can support infinite optical modes in principle, is an effective way to generate multiplexed entanglement. Enhancing the channel number of OAM multiplexed entanglement is crucial for developing high-capacity quantum information protocols. In this study, we experimentally implement 29 pairs of continuous variable entangled OAM modes in the range of topological charge l from -14 to 14. By utilizing the Bessel?Gaussian modes, whose beam size increases at a slower rate with the increase of the value of l compared to the Laguerre?Gaussian modes, we experimentally realize the enhancement of channel number of OAM multiplexed entanglement. This method provides an effective solution for enhancing the data-carrying capacity of quantum information communication systems.
