论文摘要
提供非古典光状态的来源的发展是光学量子信息科学应用的主要需求之一。在这里，我们通过使用高阶谐波生成过程来证明使用驱动固态系统的强激体磁场的非古典光状态，在该过程中，电子隧道从父站点出发，然后在其发射高阶谐光辐射上重新组合，以影响驱动驾驶激光场的费用。由于在固态系统中，可以将电子的重组沿材料定位，因此电子的最终状态确定了由于激光 - 物质相互作用，电磁场如何受到影响，从而导致电子与田地之间产生纠缠。可以通过应用调节操作，即基于高谐光辐射的测量来增强这些特征。我们研究最终量子光学状态中存在的非古典特征，并表征了固体中光和电子之间的纠缠量。这项工作为使用强场物理学开发紧凑型固态的非经典光源奠定了基础。
The development of sources delivering non-classical states of light is one of the main needs for applications of optical quantum information science. Here, we demonstrate the generation of non-classical states of light using strong-laser fields driving a solid-state system, by using the process of high-order harmonic generation, where an electron tunnels out of the parent site and, later on, recombines on it emitting high-order harmonic radiation, at the expense of affecting the driving laser field. Since in solid-state systems the recombination of the electron can be delocalized along the material, the final state of the electron determines how the electromagnetic field gets affected because of the laser-matter interaction, leading to the generation of entanglement between the electron and the field. These features can be enhanced by applying conditioning operations, i.e., quantum operations based on the measurement of high-harmonic radiation. We study non-classical features present in the final quantum optical state, and characterize the amount of entanglement between the light and the electrons in the solid. The work sets the foundation for the development of compact solid-state-based non-classical light sources using strong-field physics.
