论文摘要
已经提出了固体中的原子样量子系统作为原子钟的紧凑替代方案，但是意识到固态技术的潜力将需要一种结构设计，该设计克服了传统限制，例如磁性和温度引起的系统。在这里，我们提出了一个解决此问题的解决方案：一个“固态自旋时钟”，该时钟将微波谐振器与磁场不敏感的自旋跃迁在钻石氮 - 脱位中心的基础状态内。该“二极化稳定的”旋转时钟（PSSC）的详细数值和分析模型表明，假设当前的实验参数，在1秒测量时间下，潜在的分数频率不稳定性低于$ 10^{ - 13} $。在微型原子蒸气时钟中，这种稳定性将代表对最先进的最先进的改善。
Atom-like quantum systems in solids have been proposed as a compact alternative for atomic clocks, but realizing the potential of solid-state technology will requires an architecture design which overcomes traditional limitations such as magnetic and temperature-induced systematics. Here, we propose a solution to this problem: a `solid-state spin clock' that hybridizes a microwave resonator with a magnetic-field-insensitive spin transition within the ground state of the diamond nitrogen-vacancy center. Detailed numerical and analytical modeling of this `polariton-stabilized' spin clock (PSSC) indicates a potential fractional frequency instability below $10^{-13}$ at 1 second measurement time, assuming present-day experimental parameters. This stability would represent a significant improvement over the state-of-the-art in miniaturized atomic vapor clocks.
