量子力学和引力的统一仍然是当今物理学的主要挑战之一。受量子引力启发的唯象模型为探索量子引力的潜在方面提供了一个窗口，包括可以通过实验测试的定性新行为。一个这样的唯象模型是广义测不准原理，它预言了一个修改的海森堡测不准关系和一个变形的正则交换子。最近的研究表明，光学机械系统提供了重要的承诺，把严格的实验界限，这样的模型。在本文中，我们介绍了一个计划，以增加这些实验的灵敏度与脉冲光机械相互作用的扩展序列。我们还分析了光相位噪声和光损耗的影响，并提出了一种策略，以减轻这种有害的影响。
The unification of quantum mechanics and gravity remains as one of the primary challenges of present-day physics. Quantum-gravity-inspired phenomenological models offer a window to explore potential aspects of quantum gravity including qualitatively new behavior that can be experimentally tested. One such phenomenological model is the generalized uncertainty principle, which predicts a modified Heisenberg uncertainty relation and a deformed canonical commutator. It was recently shown that optomechanical systems offer significant promise to put stringent experimental bounds on such models. In this paper, we introduce a scheme to increase the sensitivity of these experiments with an extended sequence of pulsed optomechanical interactions. We also analyze the effects of optical phase noise and optical loss and present a strategy to mitigate such deleterious effects.
