我们描述了光学参量振荡器偏振模和轨道角动量模中的连续变量超纠缠。推导并求解了多模参量相互作用的量子随机方程，计算了表征连续变量纠缠的正交噪声谱。作为主要结果，我们预测的振幅和相位正交的相互作用模式的不同组合之间的同时纠缠。我们还提出了实验装置来访问不同种类的纠缠。
We describe continuous-variable hyperentanglement in polarization and orbital angular momentum modes of an optical parametric oscillator. The quantum stochastic equations for the multimode parametric interaction are derived and solved allowing for calculation of the quadrature noise spectra that characterize continuous-variable entanglement. As a main result, we predict simultaneous entanglement between different combinations of amplitude and phase quadratures of the interacting modes. We also propose experimental setups to access the different kinds of entanglement.
