论文摘要
探索神秘的暗物质是现代物理学的关键追求。当前，由于其弱相互作用的性质，检测轴是一种假设粒子作为暗物质的主要组成部分，仍然是一个重大挑战。在这里，我们在量子水平上表明，在磁场渗透的空腔中，单轴 - 光子转换率通过空腔质量因子提高，并且在定量上大于经典结果$π/2 $。可以将轴腔视为一种量子设备，该量子设备发出具有时间分离的单个光子。这与经典图片有所不同，并揭示了轴突腔实验在量子水平上处理信号灵敏度的可能性，例如，具有交叉功率和二阶相关测量值的双路径量子干涉测量值。该方案将大大减少信号扫描时间，并提高轴轴耦合的灵敏度，并有可能导致直接观察轴。
Exploring the mysterious dark matter is a key quest in modern physics. Currently, detecting axions, a hypothetical particle proposed as a primary component of dark matter, remains a significant challenge due to their weakly interacting nature. Here we show at quantum level that in a cavity permeated by a magnetic field, the single axion-photon conversion rate is enhanced by the cavity quality factor and is quantitatively larger than the classical result by $π/2$. The axion cavity can be considered a quantum device emitting single photons with temporal separations. This differs from the classical picture and reveals a possibility for the axion cavity experiment to handle the signal sensitivity at the quantum level, e.g., a dual path quantum interferometry with cross-power and second-order correlation measurements. This scheme would greatly reduce the signal scanning time and improve the sensitivity of the axion-photon coupling, potentially leading to the direct observation of axions.
