论文摘要
时间信号的产生是科学中的一项基本任务。在这里，我们研究了时间信号的质量与产生它的系统物理学之间的关系。根据量子理论，任何时间信号都可以分解为单个量子，从而导致单个检测事件。我们的主要结果是这些事件的及时峰值的峰值，这取决于信号发生器的维度。该结果有望在各种方向上应用，包括信息理论，量子时钟和过程模拟。
The generation of time signals is a fundamental task in science. Here we study the relation between the quality of a time signal and the physics of the system that generates it. According to quantum theory, any time signal can be decomposed into individual quanta that lead to single detection events. Our main result is a bound on how sharply peaked in time these events can be, which depends on the dimension of the signal generator. This result promises applications in various directions, including information theory, quantum clocks, and process simulation.
