论文摘要
该事件视野通过鹰效应产生量子相关性是众所周知的。但是,我们认为,可以通过适当阐明地平线来根据需要调制纠缠的创建。我们从量子信息理论中适应技术来量化鹰派过程中产生的纠缠,并表明,尽管环境热噪声(例如,CMB辐射)降低了它,但使用挤压输入的使用可以以受控的方式提高内部和外部区域之间的非分离性。我们进一步将我们的想法应用于在实验室炮制的模拟事件视野中,并坚持认为,调整纠缠产生的能力为检测难以捉摸的鹰效应的量子签名提供了有希望的途径。
That event horizons generate quantum correlations via the Hawking effect is well known. We argue, however, that the creation of entanglement can be modulated as desired, by appropriately illuminating the horizon. We adapt techniques from quantum information theory to quantify the entanglement produced during the Hawking process and show that, while ambient thermal noise (e.g., CMB radiation) degrades it, the use of squeezed inputs can boost the non-separability between the interior and exterior regions in a controlled manner. We further apply our ideas to analog event horizons concocted in the laboratory and insist that the ability to tune the generation of entanglement offers a promising route towards detecting quantum signatures of the elusive Hawking effect.
