论文摘要
我们研究了由于重力引起的纠缠动力学的影响 - 通用反应机理的基础 - 对地球重力场中的马赫 - 泽尔德和洪 - 乌尔曼德尔干涉测定学中的光子状态和量子记忆的效果。我们表明，在Hong-Ou-Mandel干涉法中，通过近距离技术的影响很有可能。这将代表理论建模的实验检验，该测试结合了由光理论和一般相对性预测的效果预测的多粒子效应。我们的文章代表了对基于空间量子记忆的相对论重力影响的首次分析，这将是全球量子通信网络的重要成分。
We investigate the effect of entanglement dynamics due to gravity -- the basis of a mechanism of universal decoherence -- for photonic states and quantum memories in Mach-Zehnder and Hong-Ou-Mandel interferometry setups in the gravitational field of the earth. We show that chances are good to witness the effect with near-future technology in Hong-Ou-Mandel interferometry. This would represent an experimental test of theoretical modeling combining a multi-particle effect predicted by the quantum theory of light and an effect predicted by general relativity. Our article represents the first analysis of relativistic gravitational effects on space-based quantum memories which are expected to be an important ingredient for global quantum communication networks.
