我们提出了一个可行的方案，远程制备三维（3D）光学涡旋线。我们的方案依赖于完整的描述高维轨道角动量（OAM）纠缠的拉盖尔-高斯模式。理论上证明了通过改变泵浦光的束腰，我们可以远程制备出三维形貌的涡旋态的目标光子，表现为扭曲的涡旋链、分离的涡旋环、涡旋链或涡旋结。此外，我们利用双光子Klyshko图像来说明OAM指数ε的守恒律和径向模指数p的扩展效应，其中施密特数的计算显示了本远程态制备中涉及的量子信道的高维容量.
We propose a feasible scheme to remotely prepare three-dimensional (3D) optical vortex lines. Our scheme relies on the complete description of high-dimensional orbital angular momentum (OAM) entanglement in terms of the Laguerre-Gaussian modes. It is theoretically demonstrated that by simply changing the pump beam waist, we can remotely prepare the target photons in the vortex states of 3D interesting morphology, appearing as twisted vortex strands, separated vortex loops, and vortex link or knot. Furthermore, we employ the biphoton Klyshko picture to illustrate the conservation law of the OAM index ℓ and the spreading effect of the radial mode index p, where the Schmidt numbers are calculated to show the high-dimensional capacity of the quantum channels involved in the present remote state preparation.
