标题： Noiseless signal amplification in an opto-mechanical transducer

摘要： 通过使用共振光学参量换能器，作用于量子振荡器的共振经典力的高灵敏度量子检测可以得到显著增强。 我们证明，这种方法不仅能够实现突破标准量子极限灵敏度的量子反作用规避测量，还能促进经典信号的无噪声放大。 这种放大是通过独立测量由信号力产生的两个调制边带实现的，从而实现更精确且抗噪的检测过程。 显示英文摘要

摘要： The high-sensitivity quantum detection of a resonant classical force acting on a quantum oscillator can be substantially enhanced through the use of a resonant optical parametric transducer. We demonstrate that this approach not only enables quantum back-action evasion measurements that exceed the Standard Quantum Limit of sensitivity but also facilitates the noiseless amplification of the classical signal. This amplification is achieved by independently measuring the two modulation sidebands generated by the signal force, allowing for a more precise and noise-resistant detection process.
