量子不等式在量子光学中的应用

Application of quantum inequalities to quantum optics

P. Marecki

摘要:

我们在量子光学实验中建立了量子不等式(从弯曲时空的量子场论中得知)和压缩度之间的联系。我们证明了一个不等式,它将电场波动的减少与它们的持续时间联系在一起。波动抑制水平越大,持续时间越短。作为这个不等式在相位控制精度为1%的压缩光的情况下的应用的一个例子,我们导出了允许的压缩度的极限为-15dB。

英文摘要:

We establish a connection between quantum inequalities (known from quantum field theory on curved spacetimes) and the degree of squeezing in quantum-optical experiments. We prove an inequality which binds the reduction of the electric-field fluctuations to their duration. The bigger the level of fluctuations-suppression the shorter its duration. As an example of the application of this inequality in the case of squeezed light whose phase is controlled with 1% accuracy we derive a limit of -15dB on the allowed degree of squeezing.
