AI 中文摘要
寻求量子引力理论仍然是现代物理学的核心挑战，其目标在于统一广义相对论与量子力学。由于普朗克尺度难以触及，直接实验观测量子引力效应极为困难。然而，最近的提议表明，通过先进的量子干涉技术实现的两个大质量粒子之间的引力诱导量子纠缠，可以为引力的量子性质提供经验证据。我们证明，干涉仪的几何构型在纠缠产生中起着决定性作用。我们的分析揭示，几何优化可以显著增强引力诱导的相移，从而改善引力介导纠缠实验探测的前景。此外，我们表明，先前提议中采用的标准近似可能严重限制预测精度并危及实验可行性。
英文摘要
The quest for a quantum theory of gravity remains a central challenge in modern physics, driven by the goal of unifying general relativity and quantum mechanics. Direct experimental access to quantum gravitational effects is notoriously difficult due to the inaccessibility of the Planck scale. Recent proposals, however, suggest that gravitationally induced quantum entanglement between two massive particles, realized through advanced quantum interferometric techniques, could provide empirical evidence for the quantum nature of gravity. We demonstrate that the geometrical configuration of an interferometer plays a decisive role in entanglement generation. Our analysis reveals that geometric optimization can substantially enhance the gravitationally induced phase shift, thereby improving the prospects for experimental detection of gravity-mediated entanglement. Moreover, we show that standard approximations employed in prior proposals may severely limit predictive accuracy and compromise experimental feasibility.
