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 |l|. In addition, we investigate...
