Accelerated light has been demonstrated with laser light and diffraction. Within the diffracting field it is possible to identify a portion that carries most of the beam energy, which propagates in a curved trajectory as it would have been accelerated by a gravitational field for instance. Here, we analyze the effects of this kind of acceleration over the entanglement between twin beams produced in spontaneous parametric down-conversion. Our results show that acceleration does not affect entanglement significantly, under ideal conditions. The optical scheme introduced can be useful in the understanding of processes in the boundary between gravitation and quantum physics.

加速光的光子纠缠

加速光已通过激光和衍射得到证明。在衍射场内，可以识别携带大部分光束能量的部分，该部分以弯曲的轨迹传播，就像它会被重力场加速一样。在这里，我们分析了这种加速度对自发参数下转换中产生的双光束之间的纠缠的影响。我们的结果表明，在理想条件下，加速度不会显着影响纠缠。引入的光学方案有助于理解引力和量子物理之间的边界过程。
