从理论上研究了自适应光学（AO）在保护高维光子轨道角动量（OAM）态纠缠不受相干性相位畸变影响方面的潜力。我们证明，AO是能够减少OAM模式之间的串扰，因此，纠缠衰减以及光子损失。对高维贝尔不等式的AO稳定的输出状态的测试表明，传输的纠缠允许安全通信，即使在强闪烁制度。
We theoretically study the potential of adaptive optics (AO) to protect entanglement of high-dimensional photonic orbital-angular-momentum (OAM) states against turbulence-induced phase distortions. We demonstrate that AO is able to reduce crosstalk among the OAM modes and, consequently, the entanglement decay as well as photon losses. A test of the AO-stabilized output state against high-dimensional Bell inequalities shows that the transmitted entanglement allows for secure communication, even in the strong scintillation regime.
