论文摘要

将单个量子的激发添加或减去骨气系统的热状态具有相反的效果,即大约将其平均职业增加一倍。我们通过在光学窃窃私语的微孔子中通过Brillouin Optomegranics实施了机械振荡器的热状态,通过在机械振荡器的热状态下实现单程添加和减去此效果的第一个实验演示。使用将单光子计数和光学杂差检测结合的检测方案,我们观察到机械热波动的加倍至高精度。该联合点击-DYNE检测方案的功能为光学量子科学和应用增加了一个重要的新维度。

Adding or subtracting a single quantum of excitation to a thermal state of a bosonic system has the counter-intuitive effect of approximately doubling its mean occupation. We perform the first experimental demonstration of this effect outside optics by implementing single-phonon addition and subtraction to a thermal state of a mechanical oscillator via Brillouin optomechanics in an optical whispering-gallery microresonator. Using a detection scheme that combines single-photon counting and optical heterodyne detection, we observe this doubling of the mechanical thermal fluctuations to a high precision. The capabilities of this joint click-dyne detection scheme adds a significant new dimension for optomechanical quantum science and applications.
