利用弱测量放大单光子非线性

Amplifying Single-Photon Nonlinearity Using Weak Measurement

Amir Feizpour, Xingxing Xing, Aephraim M. Steinberg

摘要:

我们表明,弱测量可以用来“放大”光学非线性在单光子水平,这样的效果,一个适当的后选择的光子对经典光束可能是大的许多非后选择的光子。我们发现,“弱值放大”提供了一个显着的改善,在信噪比的技术噪声与长相关时间的存在。与以前的弱测量实验不同,我们提出的方案没有经典等效方案。

英文摘要:

We show that weak measurement can be used to "amplify" optical nonlinearities at the single- photon level, such that the effect of one properly post-selected photon on a classical beam may be as large as that of many un-post-selected photons. We find that "weak-value amplification" offers a marked improvement in signal-to-noise ratio in the presence of technical noise with long correlation times. Unlike previous weak measurement experiments, our proposed scheme has no classical equivalent.
