真空中光速测量的固有误差

Intrinsic measurement errors for the speed of light in vacuum

Daniel Braun, Fabienne Schneiter, Uwe R. Fischer

摘要:

真空中的光速是最重要和最精确测量的自然常数之一,按照惯例固定为$c=299 792 458$ m/s。先进的理论预测可能偏离这个普遍的价值,甚至量子波动的$c$。结合量子参数估计理论和经典广义相对论的观点,我们在这里严格地建立了真空中光速在给定时空区域内的不确定性的下界的存在,并受到一些合理的限制。它们为时空量子涨落预测的实验可证伪性提供了一个新的视角。

英文摘要:

The speed of light in vacuum, one of the most important and precisely measured natural constants, is fixed by convention to $c=299 792 458$ m/s. Advanced theories predict possible deviations from this universal value, or even quantum fluctuations of $c$. Combining arguments from quantum parameter estimation theory and classical general relativity, we here establish rigorously the existence of lower bounds on the uncertainty to which the speed of light in vacuum can be determined in a given region of space-time, subject to several reasonable restrictions. They provide a novel perspective on the experimental falsifiability of predictions for the quantum fluctuations of space-time.
