摘要：
高效且低误报率地探测单个能量量子具有重要的科学意义，从作为光学和红外光子的单量子传感器，到直接探测低质量暗物质。我们确认了在由Mn$_{12}$-acetate制成的单分子磁体（SMM）晶体中，由量子散射引发的磁雪崩的初步实验演示，首次确立了使用SMM作为粒子探测器。尽管当前装置的能量阈值在MeV量级，我们的结果激励了探索多种SMM材料，其性质可能允许探测亚eV能量沉积。
英文摘要：
The detection of a single quantum of energy with high efficiency and a low false positive rate is of considerable scientific interest, from serving as single quantum sensors of optical and infra-red photons to enabling the direct detection of low-mass dark matter. We confirm our initial experimental demonstration of magnetic avalanches induced by scattering of quanta in single-molecule magnet (SMM) crystals made of Mn$_{12}$-acetate, establishing the use of SMMs as particle detectors for the first time. Although the current setup has an energy threshold in the MeV regime, our results motivate the exploration of a wide variety of SMMs whose properties could allow for detection of sub-eV energy depositions.
