摘要

利用铷蒸气中的四波混合过程，实验产生了9组轨道角动量复用的四束正交压缩。四束正交压缩的程度随着拓扑电荷|和|的增加而减小。此外，我们还研究了具有OAM叠加模态的四束正交压缩。我们的研究结果提供了一种有效的方法来产生OAM复用多波束正交压缩，并可能在多参数估计中找到潜在的应用。

Experimental realization of orbital angular momentum multiplexed four-beam quadrature squeezing

We experimentally generate 9 sets of orbital angular momentum (OAM) multiplexed four-beam quadrature squeezing by utilizing four-wave mixing processes in a rubidium vapor. The degree of four-beam quadrature squeezing decreases with the increase of topological charge

. In addition, we investigate the four-beam quadrature squeezing with OAM superposition modes. Our results provide an efficient way to generate OAM multiplexed multi-beam quadrature squeezing and may find potential applications in multi-parameter estimation.
