我们报告的电子自旋共振测量施主硅在毫开尔文温度下使用超导$LC$平面微谐振器和约瑟夫森参量放大器。谐振器包括纳米线电感器，其限定了飞升检测体积。由于衬底中的应变，施体共振线被严重加宽。单自旋光子耦合强度高达$\sim 3~\text{kHz}$观察。单次激发灵敏度为$120 \pm 24~$spins/Hahn回波，对应于重复采集的$\approx 12 \pm 3$~spins$/\sqrt{\text{Hz}}$。
We report electron spin resonance measurements of donors in silicon at millikelvin temperatures using a superconducting $LC$ planar micro-resonator and a Josephson Parametric Amplifier. The resonator includes a nanowire inductor, defining a femtoliter detection volume. Due to strain in the substrate, the donor resonance lines are heavily broadened. Single-spin to photon coupling strengths up to $\sim 3~\text{kHz}$ are observed. The single shot sensitivity is $120 \pm 24~$spins/Hahn echo, corresponding to $\approx 12 \pm 3$~spins$/\sqrt{\text{Hz}}$ for repeated acquisition.
