论文摘要
重力分解的模型通常不适用于包括光子在内的超偏见系统。结果，很少开发出重力分解的量子光学测试。在本文中，我们将Anastopoulos和Hu（Arxiv：1305.5231）的重力解谐度模型推广到光子。在此模型中，破坏性源自随机引力扰动的浴，可能是基本起源。我们得出电磁（EM）场一般状态的主方程；唯一的自由参数是引力波动的噪声温度$θ$。我们发现，对长基线的干扰实验原则上可以在$θ$中产生强大的限制。
Models of gravitational decoherence are not commonly applied to ultra-relativistic systems, including photons. As a result, few quantum optical tests of gravitational decoherence have been developed. In this paper, we generalize the gravitational decoherence model of Anastopoulos and Hu (arXiv:1305.5231) to photons. In this model, decoherence originates from a bath of stochastic gravitational perturbations, possibly of fundamental origin. We derive a master equation for general states of the electromagnetic (EM) field; the only free parameter is a noise temperature $Θ$ of the gravitational fluctuations. We find that interference experiments with long baselines, accessible in near-future experiments, can, in principle, lead to strong constraints in $Θ$.
